Fix local weapon sounds (like deploy sounds) playing twice on high ping

 - No need to send the sound event from the server when the sound is only going to be heard on the client anyway
 - Also made the sound play for observers if WeaponSoundLocal is called on their client, too (not a guarantee)
  + Could potentially be improved for observers by playing the sound on the client for the local player and sending the sound to observers on the server
