Bug 13487: DT pagination contains '...' for the full_numbers form

Since the DT upgrade (bug 12986), the full_numbers pagination adds a
span (containing '...'). It is not managed by the css file and is put at
the end of the page numbers ( "1 2 3 4 5 20 NEXT LAST ...", we expect "1
2 3 4 5 ... 20 NEXT LAST").

Test plan:
1/ Go on the member search and launch a search which will return more than
7 pages
2/ Without this patch, the '...' span is put at the end of the
pagination bar.
3/ With the patch it should be better placed.
