Ticket #48146 - async simple paged results issue
Description: commit 5e9c4f1f09596dd076a6c3a0bb419580e8fd705e broke the
CI test case ticket47824_test.py.
If the simple paged results search is operated on a backend having one
or more sub-backends underneath, it fails to pick up the next sub-back
ends, but repeats the search on the parent backend. The problem was
fixed.
