[#47984789] Make unit tests pass again (Jenkins)
[#46718781] fixed sticky button
Fixed so called getUrl bug for menu entries; in fact, when creating menu items, Karybu (aka XE) put a "index.php?module=admin&act=disp<whatever>" link into database directly, should instead call getUrl.
Please notice that in order for this fix to work, a new database is required, thus the previously  wrong inserted urls won't affect the menu links.

[#46718781] fixes
fixed again the so called getUrl bug; now the complaint was about the links from the rightmost menu bar (they had the installation folder specified twice); my solution here would be that in the database we should store links relative to the site root and get rid of 'getFullUrl" when composing the link.
