Defining a menu with scope wiki on a sub-wiki requires programming rights

Steps to reproduce :

• From a new instance, create a new user on the main wiki, and a sub-wiki
• Install the menu application on the sub-wiki (do it with the global administrator which has PR, to make sure that this issue isn't linked to a rights issue at install)
• Make sure that the new user is admin of the subwiki
• With the new user, create a menu with a display localtion (for instance, After the Page Header), and scope "wiki"

Expected : the menu is displayed for everyone on the sub-wiki.

Actual : even though we see that a space appeared for the menu in the sub-wiki UI, the contents of the menu are not displayed.

Saving the menu with a global admin (having PR) solves the issue.
