Remove particles involving view model when deploying a new weapon

This fixes the "Cannot update control point 1 for effect 'muzzleflash_pistol/smg/rifle/shotgun'" message spam on the client.

Nice one! I procrastinated finding that shit for years.

But yea I'm sure it's fine ship it.

[TomyLobo]

Already shipped it anyway :)

And yeah I could see why you procrastinated it :D

This didn't fix the issue entirely, but the spam is down to half a page on very rare occasions. I think it still happens if you die and there are still particles.

I implemented another fix and I drilled down to some even weirder messages... I think I fixed it this time :)

I get rare instances of these:

Model '(null)' doesn't have attachment 'muzzle' to attach particle system 'muzzleflash_pistol' to.
Cannot update control point -1 for effect 'muzzleflash_pistol'.
Cannot update control point 1 for effect 'tracer_bullet'.
