I have a google account setup in gnome online accounts.  I use said google account in evolution and empathy.

Two days ago I changed the password of the google account, using a browser.

Evolution or gnome online accounts never prompted me for a password.  The cached token was, I presume, still valid while the laptop was powered on.

This morning evolution started giving timeout errors on imap.gmail.com.

I couldn't find any way to disconnect / reconnect / forget the password.  Not in Evolution, nor in settings -> online accounts, nor in seahorse.

I could delete the token in seahorse, but still gnome online accounts wouldn't prompt for a new password.  It would just timeout with empty tokens.

I could only reset the password by deleting the account, and recreating it.

So two bugs:
1. "timeout" is the wrong error.
2. "logout"/"re-prompt password" should be possible somewhere.
