[Bug] Deleting shared calendar leads to exception for viewing the shared calendars

[1Luc1]

Steps to reproduce:

1. Create calendar A for one user X.
2. Share this calendar A with other user Y.
3. Delete calendar A from user X.
4. Try to view shared calender for user Y.
5. Exception occurs: An exception has been thrown during the rendering of a template ("Entity of type 'App\Entity\Calendar' for IDs id(8) was not found

Expected behavior: Delete shared calenders

Version: Davis v3.3.0

Side Node:
There is a calendarsubsriptions entity, which (for my use case) is never used/filled and the calendar delete action method does check this entity and deletes it if entries exits. For what is this used?

Would you mind checking that #103 fixes your issue?
