The backups pagination was with a bug that prevents users from
access older backups when the number of backups exceeds the
page size configurated in 'API_RESULT_PAGE_SIZE' properties.
The bug was occurring because the pages displays (Next, Prev) were
not displayed in the backups page, leaving the user with only
the first page to access their backups, so the backups from other
pages are unreachable.
Was fixed this bug and also was added new buttons to access
a specific, the last and the first pages. Easing the users'
navigation through the backups pages.
