Fix function 'addLiquidityReturn' to take all reserve tokens and their corresponding amounts instead of a single reserve token and its corresponding amount (in the V1-Pool-Converter contract and in the Standard-Pool-Converter contract).
Fix all web3 calls to functions 'addLiquidity' and 'removeLiquidity' by stating the overloaded version of each function explicitly (in the test of the Standard-Pool-Converter contract and in the test of the Fixed-Rate-Pool-Converter contract).
