Mike Frysinger 6da17751ca prune: handle branches that track missing branches
Series of steps:
* Create a local "b1" branch with `repo start b1` that tracks a remote
  branch (totally fine)
* Manually create a local "b2" branch with `git branch --track b1 b2`
  that tracks the local "b1" (uh-oh...)
* Delete the local "b1" branch manually or via `repo prune` (....)
* Try to process the "b2" branch with `repo prune`

Since b2 tracks a branch that no longer exists, everything blows up
at this point as we try to probe the non-existent ref.  Instead, we
should flag this as unknown and leave it up to the user to resolve.

This probably could come up if a local branch was tracking a remote
branch that was deleted from the server, and users ran something like
`repo sync --prune` which cleaned up the remote refs.
