Bug 25005: (bug 22868 follow-up) Fix suggestions pending on main page

There is a "Suggestions pending approval" link on the main page that is
displayed if there are new suggestions and the logged in user has the
permission to manage them.

On bug bug 22868 the permission changed from
acquisition.suggestions_manage to suggestions.suggestions_manage

But in the template, one occurrence has not been replaced correctly
(certainly because it was already wrong actually).

Test plan:
Create a suggestion at the OPAC
Create a patron with the suggestions permission
Use this patron to login at the staff interface
=> Without this patch the link does not appear on the main page
=> With this patch applied the link appears
