repo: skip invalidation of changelog if it has 'delayed' changes (API)
The changelog object can store recently added revisions in memory
until the transaction is committed. We don't want to lose those
changes even if repo.invalidate(clearfilecache=True), so let's skip
the changelog when it has such 'delayed' changes.
