Improve project_with_board factory to create the default lists

## What does this MR do?

Create the default lists after creating a project with the `project_with_board` factory. This makes the setup phase on tests be more simpler.

## Why was this MR needed?

These two lists are present in every issue board, so we don't have to create them manually in every test.

Fixed awards dropdown search text from repeating

## What does this MR do?

Thanks @zeiv for this!

>This fixes #20463 by adding the .emoji-search class to the "Search results" h5 element.  AwardsHandler.prototype.setupSearch() was trying to remove the element before creating a new one, but wasn't because the it was attempting to select it with the .emoji-search class, which wasn't being added.

## Are there points in the code the reviewer needs to double check?

>I don't believe so.

## Why was this MR needed?

Fixed list issues not loading with spaces in filtered values

## What does this MR do?

Vue resource is very kindly encoding our URL params when sending. However - we didn't actually want the `+` to be encoded because Rails reads that as a space, but doesn't read the encoded value as a space 😕 

This converts the `+` into spaces 👍

Robots and browsers should not crawl and remember deploy page

## What does this MR do?

Changing meta information for robots and browsers not to remember a page during deployment

## Why was this MR needed?

User browsers and robots takes the page content as accurate during deployment - HTTP code 200 is send to browser, it's all being remembered.

See merge request !5842

- The commit count was capped at 10, due to
  `Gitlab::Git::Repository#log` enforcing a limit, with the default set
  to 10.

- Reimplement a small portion of this `log` function to get just the
  data we need.

Update sprockets version to 3.7.0

Closes #22277

Update robots.txt disallow to allow users/groups starting with "s"

## What does this MR do?

Update robots.txt "Disallow: /s" line to "Disallow: /s/"

## Why was this MR needed?

Currently any Project that is under a username or group name that starts with "s" cannot be indexed because of this disallow line.

For example on https://gitlab.com looking at the projects with the most stars there is this project: https://gitlab.com/somerobots/Trident

If you do a Google search for "site:gitlab.com Trident", the project comes up but with "A description for this result is not available because of this site's robots.txt"

Adding the trailing slash will still disallow all snippet short urls, but start allowing projects where the URI begins with "s"

## What does this MR do?

## Are there points in the code the reviewer needs to double check?
Well, it's a one line change, so it couldn't hurt, right?

## Why was this MR needed?
Because broken links make us look like chumps. :)

## Screenshots (if relevant)

Fixes issue with rails reserved keyword type exporting/importing services.

The attribute `type`in services was being ignored by Import/Export. Added `type` as a method call in the export, as `type` gets ignored invoking `to_json`, manually adding this as a method in `import_export.yml` solves the problem. 

On a different note, I found assigning a title directly to `CustomIssueTrackerService` didn't play very well with `prop_accessor`:

```ruby
> CustomIssueTrackerService.new(title: 'asdf')
NoMethodError: undefined method `[]=' for nil:NilClass
> CustomIssueTrackerService.new(title: nil)
NoMethodError: undefined method `[]=' for nil:NilClass
```

This was also causing the Import/Export to failed... So I added a custom setter that fixed the problem.
