Fix auto-MR-close text from branch name

## What does this MR do?

Fix the MR-auto-close feature if a branch name begins with an issue IID.

It's one line, so check that line thoroughly 😃

When I create a new MR from a branch starting with an issue IID, the description doesn't get suffixed with the 'Closes #blahblah' that it should do.

Display group/project access requesters separately in admin

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

No.

## Why was this MR needed?

To not confuse access requesters with actual members.

## What are the relevant issue numbers?

Closes #18871.

[ci skip]

Rails's form helpers use the `$attr_before_type_cast` method where
available, and this value only appears to be updated on assignment, not
when the object is mutated in some other way:

    [1] pry(main)> mr = MergeRequest.new
    => #<MergeRequest:0x007fcf28395d88 ...>
    [2] pry(main)> mr.description = 'foo'
    => "foo"
    [3] pry(main)> mr.description << ' bar'
    => "foo bar"
    [4] pry(main)> mr.description
    => "foo bar"
    [5] pry(main)> mr.description_before_type_cast
    => "foo"
    [6] pry(main)> mr.description += ' bar'
    => "foo bar bar"
    [7] pry(main)> mr.description_before_type_cast

Add missing import source

I realised https://gitlab.com/projects/new is missing the `gitlab export` option, while this worked fine in GDK it seems that something was missing here.

This _should_ fix it unless I'm missing any other `import_sources` (did a grep and couldn't find it anywhere else though).
