Remove warning when playing random no-repeat sound with only 1 sound in pool

Browse source 
This makes setting up sounds for random pitch/volume faster, as you
don't have to change the mode from Random (Avoid Repeats) to Random
anymore if you only care about randomizing pitch/volume but want
to prevent a warning message from appearing on every playback.
