When new content is added to a page ( like images LazyLoading ) the
MultimediaViewer reacts mostly correctly, except that is does not
rebuild images indexes for a viewer hence breaking next/prev order.
The patch solves this by resetting the viewer state at MMVB.processThumbs()
letting the viewer to be correctly re-initialized at later stages.

Follows-up Id4df92b0ebed3 where a direct call was added into
the OO.Router.prototype which is invalid.
It also didn't add much value as it literally contains just
one line of trivial code that was already used without any
shared state with the actual instance of OO.Router used.
Use location.href directly.
