When a text is linked to a file using RTE link wizard,
linkvalidator will detect it as internal link.

[BUGFIX] Pagetree filtering crashes on draft moves

This bugfix fixes the following pagetree issues encountered in
a draft workspace:

1. Records moved in draft could not be found
2. Pagetree would crash if a moved page occurs in the rootline of
a filtered page.
3. Filtering only looked at live page title not the draft title
