Display footer only when page navigation is needed

- In manage user page, the navigation controls are only displayed in the
  section footer when there is more than one page. Issue #12677 moved
  the search form to the header, resulting in an empty footer div when
  there are 50 users or less.
- In manage tags page, the navigation controls are only displayed in the
  section footer when there is more than one page, resulting in an empty
  footer div when there are 20 tags or less.

The footer div in the above pages is now hidden when there is only one
page worth of data.

Fixes #27387
