This change moves the method resolveShortcutPage()
into PageRepository as it is now also used in determining
if a page is marked as active / current.

The method `resolveShortcutPage()` is much more convenient
when working with $page records instead of the properties,
instead of `getPageShortcut()`.

This also allows MenuProcessor to have a proper "active"
and "current" values set properly without any workarounds.
