manifestmerge: handle workdir removed, remote removed with flags

This can happen when a file with flags is removed or deleted in the working
directory and also not present in m2. The obvious solution is to add a
__delitem__ override to manifestdict that removes the file from flags if
necessary, but that has a significant performance cost in some cases, e.g.
hg status --rev rev1 --rev rev2 <file>.
