Wrote a failing test for removing interfaces from security groups
Fixed a bug where the interface <-> security group cookie id would change after interfaces had been removed from the group
Got the isolation part of removing interfaces from security groups green
Overrode the remove_interface and remove_security_group methods in the model classes. Having the paranoid plugin on the join table really throws a wrench in the inner workings of sequel. :(
Fixed a faulty test... which is green now now that it's testing what it should
and fixed another typo in a test
Removed an old TODO comment that told me to raise an error while it's better to just return nil which is the current behaviour
