Remove log assertions in chanmon_update_fail_tests

Asserting that specific log entries were printed isn't all that
useful, we should really be focusing on the expected messages (or,
when a monitor udpate fails, the lack thereof). In the next commit
one of these log checks would otherwise break due to the particular
time a monitor update fails changing, but I also plan on reworking
the montior update flows substantially soon, breaking lots of them.
