mosta fails when any experiment parameters are provided

When any experiment parameters are provided to the mosta tool it will complain that no value is specified for one of the model parameters. This happens because the ExperimentInstantiationConversion is added to the TransformationGraph but the parameters are not passed to it. This is not an issue when no experiment parameters are given because in that case the ExperimentInstantiationConversion won't be added to the TransformationGraph.
