set_current_position_from_planner() after stepper.quick_stop()

[thinkyhead]

Background: The stepper.quick_stop() method (used by M410 and the "Stop print" menu item) throws away all buffered planner moves. This causes the planner / stepper positions to become out-of-sync with the current_position.

Solution: After stepper.quick_stop() call a new function set_current_position_from_planner() which:

• waits for steppers to finish,
• sets the current_position based on the stepper positions, and
• updates the planner.position from the new current_position.

I am using Marlin 1.1.5 and if use the stop function from the lcd menu (while doing a print from ssd), the print stops immediately but the printer loses its position, to be more precise he thinks he is at a position he already left. For Example if I put this in the sd file:
G1 X100
G1 X0
and stop the print shortly after the nozzle reached X100, he will think he is at X100.
I thought this issue should be fixed?
