Expected behavior

When farmland block converts to a dirt block and a player is standing on it, cancelling PlayerTeleportEvent shouldn't cause the player to instantly die, but instead either not fire the PlayerTeleportEvent at all when pushing the player up or add another teleport cause (as right now the teleport cause is unknown) and make it so it cannot be cancelled (or just make it so the player doesn't die if cancelled).

Observed/Actual behavior

When farmland block converts to a dirt block and a player is standing on it and the PlayerTeleportEvent gets cancelled the player instantly dies (teleports in void?).

Steps/models to reproduce

1. Make a dummy plugin which cancels PlayerTeleportEvent
2. Give yourself a farmland block
3. Jump on it
