epriestley ec9eaabfbd Allow repo updates to recover after force push + garbage collection
Summary:
Fixes T5839. If a repository has been force pushed and garbage collected, we might have a ref cursor in the database which still points at the old commit (which no longer exists).

We'll then run a command like `git log <new hash> --not <old hash>` to figure out which commits are newly pushed, and this will bomb out because `<old hash>` is invalid.

Instead, validate all the `<old hash>` values before we try to make use of them.

Test Plan:
  - Forced a repository into a bad state by mucking with the datbase, generating a reproducible failure similar to the one in T5839.
  - Applied patch.
  - `bin/repository update <callsign> --trace` filtered the bad commit and put the repository into the right state.
  - Saw new commits recognized correctly.
  - Ran `bin/repository update <callsign>` for a Mercurial and SVN repo as a sanity check.
