Added tests for adding vlan(4) to a bridge and deleting from it

- add vlan(4) that has no parent interface to a bridge member
   - the vlan(4) cannot be added to a bridge member
- detach the parent interface of vlan(4) that is in a bridge member
   - vlan(4) is deleted from a bridge member at the detaching
