Encountered problem

If you set item-width in ons-carousel and execute pushPage and then execute popPage, the index of ons-carousel-item changes and the carousel moves.
This is because, when popPage is executed, setActiveIndex is always executed in onResize.

Please move the carousel before running pushPage.
