zeroconf: forward all arguments passed to ui.configitems() wrapper

f43988e5954c added 'ignoresub' argument to ui.configitems(), but zeroconf
wrapper wasn't updated. It caused the following crash:

We have no test coverage for zeroconf, so I've added a minimal test that
could reproduce this problem.
