Re-enable the code that moves the extruder during PP

Browse source 
There is frequently plenty of power left during a PP. Take advantage of
it by moving the extruder to either side of the axis to detach
completely the nozzle from the print.

Re-enable Z during this move to avoid losing the current step.
