Feature request: Send invitation mail for room changes

[brunt82]

Steps to reproduce

1. Create an appointment and add an attendee to it.
2. Attendee accepts the appointment.
3. Meeting creator (owner) changes the room of the appointment.

Expected behaviour

Nextcloud should send an e-mail about the room change as it does while changing the date or time of an appointment.

Actual behaviour

No e-mail is sent.

In my mind a room change may have the same priority like the date / time of a meeting.

Beginning with Nextcloud 9 the CalDAV server became part of Nextcloud's server and the calendar app is just a CalDAV client running in your browser.
Please report issues related to the CalDAV server in Nextcloud's server repo: https://github.com/nextcloud/server/issues

MEN! Please set policies for your own and follow them. I already open such a feature for the server and it was closed yesterday: nextcloud/server#5222
