[BUGFIX] Workspace page previews collide with generated preview links

Workspace page previews collide with that configuration that might have
been set by using a preview link containing a ADMCMD_prev command. The
keyword "IGNORE" is introduced to actually ignore these configurations
when viewing a page from the workspace module.

Resolves: #72225
Releases: master, 7.6, 6.2
