There is no longer spawn immunity after respawning

When you respawn you no longer get damage immunity. This can cause an infinite death cycle with no escaping. This is likely caused from a patch to no damage after reloading a world, MC-212.

Steps to Reproduce:

1. Set your spawn point at a bed with lava nearby
2. Jump in the lava to die
3. Jump into the lava after respawning
4. You do not have spawn immunity and take damage
