Description

Currently when MediaPageViewController.setCurrentItem is invoked shouldAutoPlayVideo parameter is ignored and MediaItemViewController.shouldAutoPlayVideo property is always set to true inside function.
In this PR I changed only part related to behaviour in MediaPageViewController.setCurrentItem but MediaPageViewController have several calls to setCurrentItem where this parameter is not used explicitly and its default to false which may alter desired final behaviour as currently MediaItemViewController.shouldAutoPlayVideo is always true. I would gladly change all places where setCurrentItem but I do not know specs.
