Fix branch remove for branches containing a '/'
Created by: Razer6
What does this MR do?
This PR removed the DOM lookup for the branch name. This is not necessary, because the element already gets a hidden
style applied.
Are there points in the code the reviewer needs to double check?
This adds a testcase, but this will fail currently. It depends on having the branch improve/awesome
on the sample repository. See https://github.com/gitlabhq/testme/issues/6
Why was this MR needed?
If the branch name contains an invalid jQuery character like /
the lookup for this element fails. As a result the element not gets removed from the DOM --> stale UX
