Summary:
- Run "phd stop" before stopping apache. This is essentially a smoke test for
PHABRICATOR_ENV being set.
- Run documentation generation after everything else. Between the pull and the
restart we have some minor exposure to APC issues with deleted files and
out-of-date module definitions, and this limits that.
- Pull commands out of (x && y) stuff, this prevents "set -e" from working
correctly.
Test Plan: Ran upgrade script locally.
