JsonQueryCosmosTest are flaky (especially on CI)

I'm going to try to skip these on the C.I., since they are passing consistently on my machine, and failing consistently on the C.I. It may be an emulator version thing, but I don't want to risk breaking my dev machine today by updating the emulator!

They failed once locally for me
