Update tile entity when interact event is cancelled.

If a plugin cancels a PlayerInteractEvent when left clicking a block the
client may have removed this block if they are in creative mode or if the
block breaks in a single hit. In this case, we need to update the client's
tile entity as well as telling it the block still exists.
