Call initialize methods with new props
Call initialize methods with new props

Both componentWillMount and componentWillReceiveProps call initialize
with props argument. Initialize did not pass these props on to
initializeFilters and initializeSorts which instad used this.props.
In the case of componentWillReceiveProps, the correct props to use to
initialize is nextProps not this.props.
