[davidsdearaujo]

Describe the bug
After sign out from a Google Account and try to login with another Google account it authenticates with the last account and don't allow the user to select another one.

To Reproduce
Steps to reproduce the behavior:

1. Login using Google OAuth: await supabase.auth.signInWithOAuth(OAuthProvider.google);
2. Fill your google credentials;
3. Sign out: supabase.auth.signOut(scope: SignOutScope.local)
4. Login again: await supabase.auth.signInWithOAuth(OAuthProvider.google);
5. The google authentication form is skipped and you are automatically logged in with the last account

Expected behavior
The user should have the ability to login with another account.
After you logout from a Google Account and try to login again you should be asked to fill the Google credentials again;

I think this is a duplicate of #1015 , because you have to sign out from the google package manually as well.

I called .signOut() from google_sign_in and it didn't resolve the problem (I'm not using supabase_auth_ui, only supabase_flutter).
