Panel display fails with script right error on pages on which the author of the panel doesn't have script rights

To reproduce:

• use a standard xwiki with the following rights:
  • admin group has view edit script admin programming everywhere
  • all group has view, edit, script everywhere
• create a new page (subtree), let's call it "P"
• don't configure panels for this page, let it inherit the ones from the wiki level
• set rights for page and children: explicitly give view, edit and script only to admin group
• with a regular user, modify one of the panels set at wiki level (for the left column, for example) - adding a comment on the panel is enough

Expected result:

• the panel in question still displays properly, on the Main page of the wiki and on page P

Actual result:

• the panel displays properly on the main page of the wiki
• the panel displays a script right error on the page P and its subtree

If, at this point, the script right is unchecked on the page P (inherited from wiki), the panel is back working on the subtree P.
