This reverts commit 6cf9fb71, reversing
changes made to 92c318af.

Preload `merge_request_diff_commits` association of each MR when
`mergeRequests` are queried via GraphQL.

We also need to batch load committers and lazy load the value of
`mergeable` and `detailed_merge_status` to prevent N+1 queries for
querying committers by their emails.
