fix: open file blocks logout

[wusteven815]

• Fixes #1685
• Delays AuthPluginPsk remount so the broadcast message is received in time

[wusteven815]

There seems to be a race condition where if a file is open, AuthPluginPsk gets destroyed before its logout event is received. This delays the state change that causes a remount, so that the logout event is reached in time.
