Sleeping players cannot be pushed

The Bug:

Sleeping players cannot be pushed.

When a villager sleeps in a bed, the player is able to push them and this is an intended mechanic as stated in MC-145707, so it seems rather strange that this similar concept doesn't apply to players.

Steps to Reproduce:

• Get two players and label them "Player A" and "Player B".
• Get "Player A" to place down a bed and begin sleeping in it.
• Get "Player B" to attempt to push "Player A" whilst they're sleeping.
• Take note as to whether or not sleeping players can be pushed.

Observed Behavior:

Sleeping players cannot be pushed.

Expected Behavior:

Sleeping players would be able to be pushed.
