Fixes file relocation pactests

This patch fixes upgrade040.py and upgrade041.py (041 now fails!):
* the old pactests didn't check the existence of the relocated file
* upgrade041.py was broken due to a typo (missing comma)

New upgrade046.py pactest was added (derived from the fixed upgrade041.py).
This fails because the file relocation check is _hacked_ to conflict.c, and
_alpm_db_find_fileconflicts is not called in case of --force.
