extruder: Verify trapq is unmodified on default SET_PRESSURE_ADVANCE

Browse source 
Check that a SET_PRESSURE_ADVANCE without an explicit EXTRUDER
parameter isn't done after the user disables or reassociates the
extruder stepper motor (via SYNC_EXTRUDER_MOTION).  Otherwise, it
could lead to very confusing results.
