[BUGFIX] Keep last opened folder in file link handler

This change uses the existing session information
(moduleData[browse_links.php][expandFolder]) to read
and write the last opened folder not just for the File
Browser (as currently used) but also the file link handler.

Resolves: #73195
Releases: master
