Fix OAuth parameters that can't be used together
Fix OAuth parameters that can't be used together

We need the "prompt" parameter, but the OAuth library we're using sets
the "approval_prompt" parameter and doesn't have an option to not set
it. So we have to either modify the library (not a great idea since the
modifications wouldn't be auto-deployed) or else tweak the auth URL once
we get it back.
