[Bug] Player will get additional DamNumTrackers if voodoo dolls are present

[StroggVorbis]

Example: MAP30: God Machine of Sunlust contains 35 voodoo dolls, which makes the player end up with 36 instances of DamNumTracker in his inventory. If he takes damage, the game will spawn 36 of the same number/s.

Worst case scenario: Enable shotgun spray and friendly fire in coop, let a fellow player hit you with the SSG. Boom, 720 DamNums.
