Custom scroll position restoration logic for Angular 2+, that doesn't consider query parameter changes in route as forward navigation, thus preventing certain scenarios where you don't want query parameter changes to scroll-to-top as they would with 'scrollPositionRestoration: enabled'.

| * When route is changed, Angular interprets a simple query params change as "forward navigation" too. | |
| * Using the pairwise function allows us to have both the previous and current router events, which we can | |
| * use to effectively compare the two navigation events and see if they actually change route, or only | |
| * the route parameters (i.e. selections stored in query params). |
