It is possible for misconfigured protected branches to have required status checks that are not in any of the current statuses: Pending, Success, Error, Failure, or Warning - presumably because the CI has not contacted us as yet.

Fix #10636 by adding case: missing StatusChecks when these are missing

* Fix wrong hint when status checking is running on pull request view

* fix lint

* fix test

* fix test

* fix wrong tmpl

* fix import

* rename function name

Once a branch has been merged if the commit ID no longer equals that of
the pulls ref commit id don't offer to delete the branch on the pull screen
and don't list it as merged on branches.

Fix #9201

When looking at the pull page we should also get the commits from the refs/pulls/x/head

Fix #9158

* Add branch protection option to block merge on requested changes.

* Add migration step

* Fix check to correct negation

* Apply suggestions from code review

Language improvement.
