Subscribing to calendars does not respect `X-WR-CALNAME` or `NAME` calendar properties

I am not sure this is the correct repo to report this, sorry if not.

Steps to reproduce

Create a new calendar in Nextcloud
Copy the private link of the calendar
Add the calendar via + -> New subscription from link

I am using a Nextcloud calendar but any endpoint with a calendar would work the same.

Expected behaviour

The calendar should be named after the X-WR-CALNAME or NAME calendar properties.

Actual behaviour

The calendar gets named after the domain name of the subscription link.

It could be argued that this is preferrable as it allows the usre to identify the calendar by the domain name instead of whatever cryptic name the ics file may contain. However, the user most probably copied the share link of the calendar from an application that already depicted the calendar name to the user and this is how the user identified the calendar they wanted to sync. Changing the name of the calendar upon subscribing in Nextcloud probably causes more confusion. Also, if the user wants to use the same calendar name as in the original app where the calendar lies, they have to go back and forth between Nextcloud and the other app, or look into the ics file which is much more complex for casual users.
