I recommend NOTIMPLEMENTEDs and filing bugs for all things that should work.
Otherwise we're going to forget them.

Ended up fixing this particular test in
https://codereview.chromium.org/2049723002/

I have avoided adding NOTIMPLEMENTED()s in other places, since they add too much
noise in the tests. But I believe I have filed bugs tracking the rest of the
things that do not currently work in mus.
