Setting the alg header to none when creating custom tokens for the emulator. This requires a recent bug fix in the google-auth package: googleapis/google-auth-library-python#729

To enable that I'm also upgrading the corresponding dependencies.

Tried to work around that issue in the tests, but it's not quite working out. Turns out google-cloud-firestore has also dropped Python 3.5 support as of their v2 release. I think we have to just drop Python 3.5 support before we can go ahead.
