Sorry for the delay. This PR somehow slipped through the cracks. It looks mostly good, but some of the tests are not relevant to the fix. And the others require some assertions. I can take another look, if those issues are addressed.

This test case is actually irrelevant to the actual fix. The fix only applies to legacy FCM APIs like sendToDevice(). It has no effect on send(). We can remove this.

We need an assertion here. May be at least .should.eventually.be.fulfilled.
