fix amendment: AMM swap should honor invariants: (#5002)

Browse Source

The AMM has an invariant for swaps where:
new_balance_1*new_balance_2 >= old_balance_1*old_balance_2

Due to rounding, this invariant could sometimes be violated (although by
very small amounts).

This patch introduces an amendment `fixAMMRounding` that changes the
rounding to always favor the AMM. Doing this should maintain the
invariant.
