Server error when setting up Gmail account: port sent to backend as string instead of integer

[kevgathuku]

Expected behavior

Setting up a Gmail account for the first time should work

Actual behavior

When setting up a new Gmail account, I get this error:

Type: TypeError
Code: 0
Message: Argument 5 passed to OCA\Mail\Service\AutoConfig\ImapConnector::connect() must be of the type integer, string given, called in /server/apps/mail/lib/Service/AutoConfig/IspDbConfigurationDetector.php on line 166
File: /server/apps/mail/lib/Service/AutoConfig/ImapConnector.php
Line: 63

The server expects the $port argument to be sent as an int but the client sends it as a string.
If you change the type of the $port variable to take a string instead of an int, the app is set up successfully.
