# What this PR does
Addresses two issues:
- addresses an internal feature request ([in
Slack](https://raintank-corp.slack.com/archives/C03KS498VGV/p1713550543916289?thread_ts=1713546008.831749&cid=C03KS498VGV))
to not have a new shift swap request auto-generated if one previously
was, but than the user decided to delete that SSR
- when disconnecting the GCal integration from your user, I've seen
cases where Google will return HTTP 400 as such ([example
logs](https://ops.grafana-ops.net/goto/8vX76pBSg?orgId=1)):
```
{'error': 'invalid_token', 'error_description': 'Token expired or
revoked'}
```
I can't seem to find detailed documentation on the revoke endpoint (`GET
https://accounts.google.com/o/oauth2/revoke?token=<token>`) to try and
better understand the possible `error` values.. but I think our best bet
here is to just continue forward w/
`user.finish_google_oauth2_disconnection_flow()` (which deletes the
`GoogleOAuth2User` associated with the user and sets
`user.google_calendar_settings = None`)
