Trying to make progress fixing broken tests

Just pushing up latest efforts. Things are still very broken.
Pass parameters to getMany
Got more tests passing. There's only one failure now!

There was a silly problem where we weren't passing arguments into getMany.

There was a really subtle problem in the stub graph: the internal toId property
on the relationship object was conflicting with the toId property from opinionData.

We were having a hard time diagnosing these issues because the service-layer tests
were not running, due to earlier failures in the integration tests. Excluding the
integration tests revealed failures in the service layer tests.
All tests passing!

Just a couple of minor typos were holding us up.
I think we're good to merge into the sortable-voting branch.
