Fix plugins not being removed when mods are deleted

Fix a recently introduced bug where deleting a mod that contains plugins
didn't remove those plugins. The delete command doesn't need to run
self.refresh() if we manually keep the plugins list in sync. Upon
removing a line that deactivated the mod before deleting it, we lost the
logic that removed plugins upon deletion.
