phabricator: update the hashes in commit messages as they get submitted Due to the sequence of actions (posting, amending the local commit, and then updating the Differential properties), the message in the commit is updated on the initial send but the message displayed in Phabricator is not. It should get updated there if the review is reposted. The data in the Commits tab is accurate for the first `phabsend`. Differential Revision: https://phab.mercurial-scm.org/D8950
