2.27.2 upgrade causes AuthError and Call to a member function ImapConnectAndLogin() on null

Describe the bug

Authentication works great with 2.24.4. Upgraded to 2.27.2 and I'm unable to authenticate with any remote server. Authentication works fine with any accounts on the local server where snappymail is installed.

I rolled back to 2.24.4 and authentication works fine again.

Logs say:

Expected behavior When logging in to any account that worked fine with 2.24.4, I'm also able to login using 2.27.2

Please complete the following information:

Browser: Firefox 111.0.1 (had reports from other users using Chrome)
IMAP daemon: dovecot
PHP version: 8.1
SnappyMail Version: 2.27.2

Additional context The auto domain grabber plugin is being used - might be related to that. No domains are defined other than 'auto' for that plugin. Even the domain we access email accounts on the local server where snappy is installed is not added to the list - it uses the auto domain grabber plugin.

Thanks as always for the assistance!
