repair: drop unnecessary phase cache invalidation

After stripping the revlogs, we have been invalidating the phase cache
since bf7b8157c483. Later, in 8e3021fd1a44, I added a call to
phasecache.filterunknown(). I apparently didn't realize it then, but I
now think that that call made the existing phasecache.invalidate()
call unnecessary, so this patch drops it. Both the test added in
bf7b8157c483 and the entire evolve extension test suite indeed still
pass.
