google import: Clean up wrong revisions
At one point, the mercurial loader was not creating the right revisions (wrong hash on parents' revision column). This resulted in wrong hashes.
This behavior is fixed with 2caf1b1fe56835b6a03f34c94dec74e514e15fbf.
We need to clean up those entries though.
Tables impacted:
- revision (entries with type 'hg')
- revision_history
