Issue filter now appends a space & the test wasn't taking this into
account when checking the value

Grapify last endpoint of the branches API

See merge request !8755

`can?` already includes the `feature_available?` check, so no need to
check this again.

In case Merge Requests are disabled on the project, no one should see
the Merge Request button.

The project was not public and this caused a 404. So the tests were
giving deceiving results.

By searching for the Merge Request button in `#content-body` this
is overcome, and also other Merge Request buttons (e.g. in the
sidebar) are ignored.
