Sometimes multiple calls necessary to getWinnerFromOracle are necessary to get the _winningOutcome to be processed:
Its not easy to determine how many times getWinnerFromOracle has to be called.
(it can be seen via emit LogWinnerKnown(winningOutcome), however this cannot be read from a smart contract)
Recommend letting the function getWinnerFromOracle return a boolean to indicate it has to be called again.
