patchbomb: add test that shows --to and --cc override matching config item

As far as I know this has always been true and is intentional (it's in
line with many other behaviors), but it wasn't tested.

# extension to emulate invoking 'dirstate.write()' at the time
# specified by '[fakedirstatewritetime] fakenow', only when
# 'dirstate.write()' is invoked via functions below:
#
#   - 'workingctx._poststatusfixup()' (= 'repo.status()')
#   - 'committablectx.markcommitted()'
