User deletion not possible in 0.7.0

[rschulzeLE]

Baikal version: 0.7.0

Expected behaviour:
User is deleted if the "Delete" button is pressed and the deletion is confirmed

Current behaviour:
Since the update to Baikal 0.7.0 an error message shows up after I try to confirm the deletion of a user. The user's ressources are deleted but the user itself still shows up in my user list. "Display name" and "Email" are empty, solely the username is still there. A second attempt to delete the user has no further effect.

The error message that shows up:

Error: Call to a member function destroy() on null in /volume1/http/baikal/Core/Frameworks/Baikal/Model/User.php:184

Stack trace:
#0 /volume1/http/baikal/Core/Frameworks/BaikalAdmin/Controller/Users.php(165): Baikal\Model\User->destroy()

Thanks for reporting. Baikal definitely needs unit tests...
The original error is not logged. What causes the first deletion to fail is the following:

ErrorException: Undefined index: calendarid in /baikal/Core/Frameworks/Baikal/Model/Calendar/Calendar.php:43
