Document the need to use a PAT with Registry when 2FA is on

Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/22465

See merge request !7874

GitLab 8.12 introduced a new permissions model which tightened the
security of Container Registry. It is now required to use a personal
token if 2FA is enabled.

Remove an order dependency in LabelsFinder specs

Makes the LabelsFinder spec expectations order-independent

There is an explicit ordering to `LabelsFinder` - title ascending - but two of the labels (a group label and a project label) have the same title, so the sort ordering isn't stable for those in all circumstances. It looks like this is intentional.

Improve the `Gitlab::OAuth::User` error message

## What does this MR do?

Fixes a logging issue submitted by a customer at https://gitlab.zendesk.com/agent/tickets/50728. 

The error saving the user is logged to application.log. Previously,
the entry had no context and was unusable - `Error saving user:
[Email address already taken]`. Adding the auth hash UID and email
makes the error more helpful.

For such a small logging change, do we need a changelog entry?

See merge request !7851

The implicit interface of project services states that the "execute"
method is meant to be called when project hooks are executed.
Currently JiraService does not support any project events even though
JiraService#supported_events says that "commit" and "merge_request"
are supported. They are only used to render correct options in
JIRA configuration screen, but they are not supported.
Because of that, this commit makes "execute" method a no-op.

Resolve "External statuses not shown correctly on pipeline page"

## What does this MR do?

Updates `generic_commit_status/_generic_commit_status.html.haml` template to match the changes made to `ci/builds/_build.html.haml` which had not previously been carried over.

## Testing

1. Ensure updated fixtures are installed (from !7792) so that these changes are made apparent.  (check out the !7792 branch if not yet merged into master, then `bundle exec rake db:drop` and `bundle exec rake dev:setup`)

2. Visit a build list page or an individual pipeline page which contains an external build status.

3. The results should look like this:

### Before:

![Screen_Shot_2016-11-28_at_9.11.27_PM](/uploads/ed8c5beb857cd17147dbddf8f5ecab1d/Screen_Shot_2016-11-28_at_9.11.27_PM.png)

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

Look for any places where these partials may be rendered to ensure external status match regular build statuses.

## Why was this MR needed?

The generic commit status template has been largely overlooked when changes are made to build table rows which should be duplicated in both places.

Fixed GFM autocomplete regex

## What does this MR do?

Their was a bug in the regex that meant it was matching from the beginning of the GFM input text. This fixes that by splitting spaces & then checking on the last match. 

It also fixes a bug where `@#` etc. would open 2 autocomplete dropdowns.
