git: Simplify handling of Gitaly::FindCommitsError
Before in !139611 (merged), we split out handling of a Gitaly::FindCommitsError
by looking
into the specific type of error. These are internal details to Gitaly
however, and there is no need to handle these errors with that level of
granularity since its logically the same error and we don't want to leak those errors from Gitaly into Rails as they are more internal details to Gitaly. Let's simplify the handling to just look for Gitaly::FindCommitsError
.
