Improvements
Speed and reliability improvements in the E2E tests. It is faster to check the status of an element on a page rather than to wait for a page reload.

We must ensure that the Merge button appears in all cases, otherwise tests will be flaky.
Involved components
gitlab/qa/qa/page/merge_request/show.rb would be the key file involved.
