[BUGFIX] Integrity constraint violation deleting resources
[BUGFIX] Integrity constraint violation deleting resources

If you have two resources using the same resource pointer,
deleting a Resource will trigger deletion of the
connected ResourcePointer which then leads to an integrity
constraint violation.

This patch tells doctrine NOT to cascade delete operations.
This will lead to orphan resource-pointers which have to
be deleted manually or on a regular base.
