Subject: [PATCH] Fix new block data for EntityChangeBlockEvent

Also standardizes how to handle EntityChangeBlockEvent before a removeBlock or destroyBlock
call. Always use 'state.getFluidState().createLegacyBlock()' to get the new state instead of
just using the 'air' state.

Also fixes the new block data for EntityBreakDoorEvent (a sub-event from
EntityChangeBlockEvent)
