Invisible weapons world model after the loser/stun animation.

[WizardoBD]

For the medigun this happens when:

-The medic heals a patient (it happens randomly but it happens)
-The medic is healing a patient and the patient respawns away from the medic while changing loadouts

For all of the other weapons (including the medigun) this happens after the player gets out of the loser/stun animation:

-After the round ends if the player in the loser animation doen't get killed he will respawn without the weapons models.
-When the player gets scared by a ghost
-When stunned by snipers huntsman taunt kill but the sniper gets killed before finishing the taunt
-Gets stunned by the sandman ball (in custom servers with the old weapons mechanics)
-When MvM Bots get stunned by Spy's sapper or get temporary disabled after capturing a gate in Mannhattan
