67fa02ed79 opus_pvq: fix PVQ search for K < 5 and low Ns 
If the PVQ search picked a place to increment/decrement on the y[]
vector which had no pulse then it would cause a desync since it would
change the sum in the wrong direction. Fix this by not considering
places without pulses as viable.

This makes the PVQ search slightly worse at K < 5 which isn't all that
common. Still, this is a workaround to prevent making broken files until
I can think of a better way of fixing it.

Also add an assertion, which can be removed or moved to assert1/2 once
the PVQ search is stable.
