The page suggest doesn't search in the page title of untranslated pages with Oracle database

Steps to reproduce:

• Setup a wiki with Oracle database.
• Create a page with title "École hôtelière" and name "ÄhmTöst".
• Create a page with content

  {{velocity}}{{html}}#pagePicker({'id': 'test'}){{/html}}{{/velocity}}

• In that picker, search for "École".

Expected result:

The created page is listed.

Actual result:

No result is listed.

Note that it plays no role that non-ASCII characters are used, the problem here is searching in the title. Searching for text in the page name works even with non-ASCII characters. As part of XWIKI-22605 an integration test has been created that tests exactly this scenario.
