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.

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

It's one line, so check that line thoroughly :smiley:

## Why was this MR needed?

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.

## What are the relevant issue numbers?

Don't think there are any.

## Screenshots (if relevant)

## Does this MR meet the acceptance criteria?

Move pre_process into render_result

This MR moves `Banzai::Renderer.pre_process` into `Banzai::Renderer.render_result`.

The `pre_process` method was called even when its output would be ignored. See 11a5a4f359ee57029dbfcc9185fc6b47243ea2aa for more details.

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
    => "foo bar bar"
