Adjust CB async teleport dismount behavior 

The expected behavior is that the entity is only dismounted
_if_ the teleport takes place, not regardless of whether
the teleport takes place.

To adhere to the expected behavior, we need to create a new teleport
flag so that the NMS teleportAsync can perform the dismount.
