rHGa2c4502e409b: narrow: only send includepats and excludepats if they are not empty

Summary

If we send an empty includepats or excludepats argument to getbundle, it's
translated to [''] on the server which causes problems because even though
it's empty, bool of that value if True and we end up creating differencematcher
with narrowspec.match() which results in unexpected behavior.
