Fix infinite scroll on uploads page

This seems to have been broken by core change I4c9f8c0c2bfd831755d4fa20a18f93fef1effd28
(see bug 24782) which got merged a week ago (explains why English Wikipedia not effected)

The new API request doesn't honour the old method. Shouldn't there have been a deprecation
notice and some compatible fallback?
