Summary:
"rev-parse --verify" is actually a terrible test, it only survived my test cases
because I put garbage into the tables with RAND() or similar, not
properly-formatted garbage.
Use "cat-file -t" instead to ensure we perform an object-existence test.
Test Plan: Ran "reconcile.php P" locally, ran "cat-file -t" and "rev-parse
--verify" on properly-formatted but invalid hashes like
"aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa", worked with @rguerin to resolve
commit issues.

Summary:
@rguerin ran into an issue in his install where Phabricator appears to have
discovered commits which no longer exist, and thus is failing to proceed with
its repository import.
It's not clear how we got into this state. Previously, it was possible by, e.g.,
parsing a different repository's working copy and then switching them back, but
there are now safeguards against that.
I'm taking a three-pronged approach to try to sort this out:
- Provide a script to get out of this state (this script) and reconcile
Phabricator's view of a repository with an authoritative copy of it. This
basically "un-discovers" any discovered commits which don't actually exist (any
queued tasks to parse them will fail permanently when they fail to load the
commit object).
- Add more logging to the discovery daemon so we can figure out where commits
came from.
- Improve Diffusion's UI when stuff is partially discovered (T776).
(This script should also clean up some nonsense on secure.phabricator.com from a
botched Diviner import.)
Test Plan: Ran "reconcile.php" with bogus commits and bogus differential/commit
links, had them expunged. Will work with @rguerin to see if this resolves
things.
