Damage Ped (NPC) desynchronization with syncer

[Toliak]

Describe the bug
Ped becomes invincible, if server will set such syncer, that the ped has not ever been on syncer's client screen

To reproduce
0. We will need 2 players

1. Create server-side ped
2. Distance between Player1 and ped must be less than draw distance
3. Rotate camera away for ped (ped must not be on Player1 client screen)
4. Restart the code (because ped must never appear on Player1 screen)
5. Damage ped by Player2 weapons: ped will be invincible. Video fragment
6. [Optional] Create server-side ped2, set aim target and fire control on Player1 client: ped is still invincible. Video fragment
7. Rotate camera to ped: now damage synchronization works well (for 5 and 6 steps)

Expected behavior
Expected from ped to be damageable.

Version
Multi Theft Auto v1.5.8-release-20779

Experiments
Here I have performed some experiments with damage synchronization. Results:

Code
Reproducing code (without Line of sight part)

Workaround
I have found similar issue: #495 ,however that issue describes case with network trouble
onClientPedDamage client-side event for all players can partially fix the problem.
