Remove search api preload for commits scope

Terri Churequested to merge
585437-remove-preload-for-search-api-commits into master

What does this MR do and why?

Remove a preload that is causing DB timeouts on GitLab.com for commits searches in the group search API.

Preload was added in !215442 (merged) which is behind a feature flag. However, the preloading is not behind a feature flag and the preloading is what's causing timeouts.

Note: the FF (#583081 (closed)) is fully enabled for a few days but the timeouts have been occurring since merge
