(Bug 56347) Enable RandomPageGenerator() and site.randompages returning more than 10 pages

API random list does not return query-continue.
We loop the query until we have our total limit exceeded.
It is on programmers side to ensure that
duplicate pages are filtered
(e.g. via DuplicateFilterPageGenerator())
