Conditional polling bug fix

[kyhy]

In the following example, if props.fetchMore is false initially and true later on, componentWillReceiveProps will error out while attempting to reassign newQueries params.

@load(props => {
  if (props.fetchMore) {
    return {
        model1: model1.getItem(),
        model2: model2.getItem()
    }
  }
  return {
      model1: model1.getItem()
  }
})
