We now ensure that if an exception is thrown while awaiting the promise,
the exception _has_ to be a revert. We throw 'Expected revert not
received' only afterwards. This solves any problems with confusing the
word 'revert'.
Fix#775
* Update StandardToken.sol
* Slight improvement in gas efficiency
Users tend to attempt to over-spend more than they attempt to burn non-burnable tokens. If the contract checks for overspending before assuring tokens are not being burnt a slight amount of gas might be saved in the long term.
* Assume that token is mintable.
* ECRecover test should revert because of wrong calldata size
* fix: use expectThrow
* fix: ignore failing test until solc^0.5.0
