feat(submit:phabricator): do not abort entire process on failure

Currently, `git submit` for Phabricator will abort the entire operation if any commit fails to be submitted. This means that if `arc diff` succeeds on one commit and then fails on its child, the entire operation is aborted. However, the first `arc diff` had side effects, so the user gets diffs uploaded to Phabricator that are not reflected locally. Instead, we should confirm any passing commits and abort after we get a failing commit. This commit updates the Phabricator forge to handle the error case better and not produce garbage commits on Phabricator.
