Replace reject_blocked with reject_blocked! in skipped callbacks.

`reject_blocked!` was introduced in c9def945, I can't find any references to `reject_blocked` ever existing.

See merge request !5532

In Rails 4.2 and below, skipping callbacks (skip_before_action, skip_after_action, etc.) that use methods which do not exist will not throw any errors.

On the other hand, Rails 5 does. See https://github.com/rails/rails/pull/19029

After testing with Rails 5 I noticed there are some methods that don't actually exist (because they were renamed, usually), this fixes a few instances of those.

reject_blocked! was introduced in c9def945, I can't find any references to reject_blocked ever existing.

Submit new issues created via the WebUI or API to Akismet for spam check on public projects.

## What does this MR do?

Submit new issues created via the WebUI by non project members to Akismet for spam check.

## Why was this MR needed?

Support for Akismet was added only to the API with !2266. This MR builds on that functionality to also check issues submitted via the WebUI for spam.

## What are the relevant issue numbers?

Related to:

- #5573 
- #5932 
- gitlab-com/infrastructure#14

Resolve "Remove routes that we do not use anymore"

_Originally opened at !4059 by @strzibny._

- - -

## What does this MR do?

> I tried to clean up the routes as mentioned in #14584
I used the following script and manually verified the changes: https://gist.github.com/strzibny/4ccbda7dcf67ef6719dcb047014e1ea7
After this patch, the script still gives me the following routes:
Unused routes (7): oauth/authorizations#show doorkeeper/tokens#create doorkeeper/tokens#revoke oauth/applications#edit oauth/applications#show doorkeeper/token_info#show omniauth_callbacks#(?-mix:(?!))
Here is a relevant code from doorkeeper on drawing these routes: https://github.com/doorkeeper-gem/doorkeeper/blob/5ea4575863781940fe6996692c6b41f2ad71d90e/lib/doorkeeper/rails/routes.rb#L25

## What are the relevant issue numbers?

Closes #14584.
