Can't delete teams with members

[jenetlan]

When trying to delete a team with members, an exception occurs. This happens both for Admins and Users (authors don't have access to that capability).

Exception:
SqlException: The DELETE statement conflicted with the REFERENCE constraint "FK_TeamMembers_Teams_Team.ID". The conflict occurred in database "PuzzleServer", table "dbo.TeamMembers", column 'Team.ID'.
The statement has been terminated.
System.Data.SqlClient.SqlCommand+<>c.b__122_0(Task result)
DbUpdateException: An error occurred while updating the entries. See the inner exception for details.
