LinqUtilsProduceProperBooleanExpressionLambda Method

Produces the proper boolean expression lambda, from the passed in lambda. If the passed in lambda's return type isn't bool it's returned as-is. Otherwise, it's checked whether it contains a boolean expression. If not, it's corrected. If it does, it's returned as-is.
