Sticky pistons should drop their block when powered by a short pulse.

[havel06]

Client version: 1.12
Server OS: Debian Linux

Expected behavior

When a sticky piston gets powered by a 2 game tick (1 redstone tick) pulse, it should push away the block directly in front of it, without retracting it back.

Actual behavior

The block gets retracted immediately.

Steps to reproduce the behavior

Place a sticky piston facing a pushable block. Power the piston with a 2 game tick pulse.

I am taking a shot at fixing the issue

Thanks for taking a look! The relevant code is in BlockPiston.h/cpp and Simulator/IncrementalRedstoneSimulator/PistonHandler.h

I reported something "similar" in #4605, if someone is interested.
Not the same behavior but it's still pistons moving a block when in vanilla they don't.
Edit: I just realised it might not be usefull as you made a PR.
