test(ohme): use charger_control_active in the #5443 dispatch-sensor tests

The tests main added in #5443 read OhmeAPI.control_active, which this branch
renamed to charger_control_active when control moved into the shared
CarChargerControl mixin. Only the attribute name changes; the assertions
are unchanged.
