[MC-125131] falling block not spawning correctly

when you spawn a falling block and assign a block to it like so:
"/summon falling_block ~ ~ ~ {Block:stone,Time:1}"

it doesn't spawn stone but just sand

Invalid. Falling block NBT was changed.

Not sure what it is now, something like ‘BlockState:{}’

I’ll see when I have access to a computer running 18w06a.

The updated command should be

/summon falling_block ~ ~ ~ {BlockState:{Name:"minecraft:stone"},Time:1}

if I'm not mistaken.
