Remove unused `resource_roundtrip()` from test suite?

[padraic-shafer]

This is not a test, and the function is not called anywhere. This dead code should probably be removed. Or could someone clarify what functionality is intended to be tested here?

databroker/databroker/tests/test_broker.py

Lines 1124 to 1138 in 23071d5

	def resource_roundtrip(broker_factory, RE, hw):
	db = broker_factory()
	db2 = broker_factory()
	from ophyd.sim import NumpySeqHandler
	import copy
	db.prepare_hook = lambda name, doc: copy.deepcopy(dict(doc))
	for spec in NumpySeqHandler.specs:
	db.reg.register_handler(spec, NumpySeqHandler)
	RE.subscribe(db.insert)
	RE.subscribe(lambda *x: L.append(x))
	uid, = get_uids(RE(count([hw.img], num=7, delay=0.1)))
	for nd in db[-1].documents():
	db2.insert(*nd)

It came in via a915611 so I think it should have been named test_resource_roundtrip 🤦🏻 .

and what I think this is testing is that the documents that come out of databroker can go back into databroker.
