Jon Cinque 75acddc100
Fix zero fee calculation (#813) 
If a swap has a trading fee and a zero owner fee, when calculating the owner
fee to pool token conversion, the simulated trading fee will be non-zero
because we floor the trading fee to 1 token.  If the input to trading
fee calculation is 0, then we will try to do `0 - 1` on an unsigned int,
which causes an underflow error.  The fix is to simply return a 0 fee
for a 0 input.
