Possible desync when tweakFreeCamera is enabled when the player dies

When you do the following steps, it causes a desync where the player's health is displayed as normal when tweakFreeCamera is enabled, but the player's health is displayed as zero when tweakFreeCamera is disabled.

Make sure you have operator status (cheats enabled in single player).
Turn on tweakFreeCamera.
Somehow kill yourself. At this point the player dies and the desync starts.
Notice that tweakFreeCamera is still turned on.
Turn off tweakFreeCamera.
Notice that the screen is shaking as if the player died and/or the player's health is displayed as 0 in the HUD.
Notice that you can't move until you die again, regardless of the tweakFreeCamera setting.
Run /kill again (with tweakFreeCamera turned off).
Notice that the desync is resolved.

Note that for step 3, you could use any of the following:

/kill: The screen shakes as if the player died, but the health bar is still normal.
/tp @p ~ ~50 ~: Fall distance is reset when tweakFreeCamera is enabled.
/effect give @p minecraft:instant_damage 1 22: Same as /kill but the health bar is displayed as 0 HP when tweakFreeCamera is disabled.
/summon zombie: The zombie attacks the real player even when tweakFreeCamera is enabled. When the player dies, it's the same as the above /effect command except that the zombie continues to attack the real (server-side) player.

I uploaded a new build which fixes this issue, as well as another (position de-sync) issue with the Free Camera mode.
Note that at least for now the Free Camera mode is still not disabled automatically when the player dies, but when you disable it manually, the camera is returned to the correct player entity.
