merge: remove unnecessary matcher checks
As part of changing manifest.diff to accept a matcher, a previous patch added
matcher calls to each location in merge.manifestmerge that tested if 'x in mf'
to maintain the same behavior as before. After analyzing it further, this
matcher call isn't needed, and in fact hurts future patches ability to use the
matcher here.
Basically, all these 'if x in mf' checks were checking if a matched file's copy
source was in the matcher as well. This meant if you passed a matcher for just
file foo, it would not return file bar even if foo was a copy of bar. Since
manifestmerge cares about copy information, let's allow all lookups of copy
sources.
We also update one spot with a 'is not None' check, since it wasn't obvious that
the value could sometimes be None before, which broke when we called
matcher(None).
A future patch adds matcher optimizations to manifestmerge which causes this
code path to get covered by existing tests.
