commit-reach(repo_get_merge_bases): pass on "missing commits" errors

Browse Source 
The `merge_bases_many()` function was just taught to indicate parsing
errors, and now the `repo_get_merge_bases()` function (which is also
surfaced via the `repo_get_merge_bases()` macro) is aware of that, too.

Naturally, there are a lot of callers that need to be adjusted now, too.

Next step: adjust the callers of `get_octopus_merge_bases()`.
