Improve Cancelled Block Place Tile Entity discardment

Browse source 
We bandaided this logic on a case by case basis before with Loot Tables and Chests,
but that is not the correct fix.

Ultimately we just needed to clear out the captured tile entity list so that the
update calls did not process the tile entity that is no longer even valid.

This solution will ensure ALL placed tile entities data is ignored and not just
the few cases we previously had filters for.
