fix market resolution - Githubissues

Fix 1:

RealityProxy.sol:

refactor the internal functions to receive the values needed (questionId, numOutcomes, etc) instead of receiving the Market. The Market is only used on resolve(), where we build the questionId based on the other values to prevent a fake market from being able to report a payout.

MarketFactory.sol:

now the questionId is calculated as keccak256( abi.encode(questionsIds, outcomeSlotCount, templateId, low, high) ). questionId, questionsIds and conditionId can be calculated from the encodedQuestions, so I removed this from the 4 factory functions and moved it to the main createMarket function. I also removed some unused parameters from the NewMarket event to avoid a stack too deep error (this same change was made on the conditional markets PR)

Market.sol:

grouped the reality and conditional tokens parameters in a struct to avoid a stack too deep error on the market factory (this same change was made on the conditional markets PR)

Fix 2:

MarketFactory.sol:

we call conditionalTokens.prepareCondition() only if the condition hasn't already been prepared. Until now the assumption was that the same market couldn't be created twice, but now that we allow the reuse of an existing conditionId it's possible to duplicate a market (we could try to avoid it, but I think the extra complexity is not worth it)
