Re-organize schema. Drop protected from runner. Add access_level to runner. Drop protected from pipeline. Add protected to ci_bilds.

Solution 1. Persists protected(ref) flag on ci_pipelines table. builds_for_shared_runner and builds_for_specific_runner read the flag instead of executing protected_for? one by one.

Ensure `issuables_count_for_state` returns the requested state count

We were incorrectly stubbing `Issues::MoveService#execute`. This only
caused a failure when another spec caused it to be autoloaded --
`spec/controllers/projects/issues_controller_spec.rb` in this case.

The assignee wasn't important to the test, and shortening the query
allowed us to avoid the "horizontal scroll" failure without having to
stub the `sidebar_collapsed?` helper.

We now document that fact.

We were essentially testing "all of the filters" four times, so now we
just do it once at the top level.
