fix(authentication): explicitly request Google auth token with provided scopes on Android

[nkalupahana]

This PR explicitly requests scopes when getting a Google access token post-Sign In with Google.

It looks like not requesting scopes explicitly works most of the time, but not all of the time. I had two users with this bug (nkalupahana/baseline#402), and this change fixed it for them (patch). This PR upstreams our patch.

Closes #725
