vcs: invalidate repo caches _after_ a push finishes
Caches were invalidated right after creating the result iterator, before
actually applying the change. Caches would thus be refreshed too early and soon
be outdated.
This bug was especially seen causing errors with missing revisions when
creating PRs right after pushing.
