By building the issue before filtering

By using `>`-quote style instead of `>>>`.

Also: Update documentation images.

So the title doesn't seem to be set _on_ a merge request.

The merge request will now always be there when the discussion was
resolved by creating a new issue.

Since the MergeRequest is now a required param for resolving discussions

Since the date would be wrong for people in different timezones.

And deduplicate the finding of MR's & discussions. Now the searching
is done in the service, istead of the controller & the API.

Delegate a discussion in a merge request into a new issue.
The discussion wil be marked as resolved and a system note will be
added linking to the newly created issue.

In EE, `@users` can be an array at the point where we remove the current
user, because it can do a permissions check on the users for project
mirroring.

Fix this in CE by only using array methods, not AR methods. We can't use
`delete` because that uses `Object#equal?`, which isn't true in this
case.
