Compute approved approver for merged MR if it is absent

Closes #9866, #9889, and #9913

See merge request gitlab-org/gitlab-ee!9648

Past merged MRs do not have approved_approvers for now,
so to keep UI display correctly, compute approved approvers if
association is empty.

Recreate fail case as spec to test creation of `approved_approver`
after merge. Use `inverse_of` to ensure same copy of MR object across
`PostMergeService` and `ApprovalMergeRequestRule`. This means we can
avoid reloading `approval_rules` to solve outdate MR merge state issue.

CE Allow Gitaly N+1 in MR CreationsController

See merge request gitlab-org/gitlab-ce!25499

The repository charts page used to detect the repository language for
each request that was made to the page. Given the detection is an
expensive operation and the same data is stored in the database the
database is now serving the request.

The same goes for an API endpoint that serves the languages.

When a repository is empty or non-existent the languages will always be
empty. And the language detection RPC isn't requested.
