OC9 - Calendar authentication credentials need to be re-entered because the calendar naming has changed

[j-ed]

Expected behavior

After upgrading from OC8.2.2 to OC9.0 it should be possible to access and use all
CalDAV calendars without re-entering the authentication credentials.

Current behavior

The authentication credentials for all subscribed calendars need to be re-entered
in e.g. Thunderbird/Lightning because the calendar naming has slightly been changed.

Example:
OC 8.x: https://your-server-url (ownCloud (Name of calendar))
OC 9.x: https://your-server-url (sabre/dav (Name of calendar))

Environment

Server Configuration

OS: Linux 3.2.75
Web server: Apache2 2.4.18

Calendar app version: 1.0.0 (20160320)
Updated from OC8.2.2

Client Configuration

Workaround is to add "$this->realm = 'ownCloud';" to the constructor in /var/www/owncloud/apps/dav/lib/connector/sabre/auth.php although now you'll get an integrity check failure. Also you have to do it every time there is an OC upgrade.
But at least you won't get calls from 100 users saying "What's this dialog when I start Thunderbird and what the hell is sabre/dav?"

I've been bitten by this too. Please consider fixing this in a 9.0 stable update
