Improve performance of user profiles, finding groups, and finding projects

This MR improves the following:

* Rendering of profile pages and Atom feeds
* Finding groups (using GroupsFinder & friends)
* Finding projects (using ProjectsFinder & friends)

Initially this MR was intended to only improve rendering of Atom feeds, but over time other fixes were introduced as well as the same code was the cause of all these problems.

Check which folders and archives should be packed before passing to tar command.

If user uses backup task with SKIP and skips one of the archives listed(uploads, builds, artifacts) backup create will give an error: `Cannot stat: No such file or directory`.

This MR fixes that by checking for skipped items.
Additionally, compact everything to avoid `TypeError: no implicit conversion of nil into String` errors.

Fix md syntax in doc/api/commits.md

Ensure variable in mail is evalled

I received this snippet in the mail:

```
Content-Type: text/plain;
 charset=UTF-8
Content-Transfer-Encoding: 7bit

Project #{@old_path_with_namespace} was moved to another location

The project is now located under
```

This MR fixes it.

Notes:

* I did a quick grep on other 'text.erb' files, but this was the only one with this type of error
* I made no changes to the specs. The only [spec](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/spec/mailers/notify_spec.rb#L412) I could find passes because (I assume) the correct value is in the html-part
