onlyPayloadSize should not be necessary with Solidity 0.5

[fulldecent]

I learned the hard way that Solidity has stronger type safety. Because it broke the ERC-165 reference implementation. The function onlyPayloadSize seems to be testing for something that Solidity now automatically tests for.

Recommendation: review if onlyPayloadSize is necessary.

Mock NMR should really be compiled with solc 0.4.11 in order to match the deployed token https://etherscan.io/address/0x1776e1f26f98b1a5df9cd347953a26dd3cb46671#code

Future improvement will be to modify compilation script to support multiple solidity versions
