[BUGFIX] Resolve shortcut to a different page in a localized page

When a page translation of type=shortcut (doktype=4)
contains a different value than its original
page, the proper target URL is now resolved correctly
upon link creation and link resolving in TSFE.

This additionally fixes flaws in the behavior of first subpage in cases where the first subpage differs between languages.
