Closes #62845

See merge request gitlab-org/gitlab-ce!29857

This `ignore_column` was present for a while but recently removed, but
to ensure we don't get error 500s let's keep it for a while.

This saves about 5 SQL calls per page if no custom appearance is
specified.

This eliminates many potential duplicate FindCommit RPCs for the same
ref, which often occurs in the RelativeLinkFilter#current_commit call.
On the GitLab 12.0 release post, for example, this would save close to
400 RPC calls.
