Database: Fix FS#13368 – use separate selected item history

Browse source 
Database and File Browser were sharing
each other’s selected item history before.

Since the database isn’t browsed
recursively, it’s probably unnecessary to
include its own history in the tree context
and its backups, saving.a little bit of memory.
