Sync code in onDestroyedByPushReaction to original

[sciwhiz12]

This PR fixes #1699 by synchronizing the code in IBlockExtension#onDestroyedByPushReaction to the original code from PistonBaseBlock (which was moved to the extension method).

Particularly, the flags passed to Level#setBlock is now a constant 18, which is the combination of Block#UPDATE_KNOWN_SHAPE and Block#UPDATE_CLIENTS.

Tested with the same reproduction steps in the linked issue, and the fix works as the sign does not pop off on piston push.
