Handle Google Scope Changed error

[MelissaAutumn]

Sentry error: https://thunderbird.sentry.io/issues/6065339480/?project=4505428124827648&query=is%3Aunresolved%20issue.priority%3A%5Bhigh%2C%20medium%5D&referrer=issue-stream&statsPeriod=14d&stream_index=6

It was mainly used to keep track of different permission states people could end up in, but we handle it on the UI-side by asking them to select everything (there's no optional permissions here!) So I think we can remove this spammy error message now.
