fix logic errors in code that determines if it's time for v10 upgrade

This would have prevented old git-annex from ever upgrading from v9 to
v10. Note that a manual `git-annex upgrade` can never run while the
assistant is running, so not <$> assistantrunning was always True,
so no matter what the timestamp of the v9 upgrade in the log, it would
decide there was old process danger.
