Using ModelViewSet or ReadOnlyModelViewSet call pagination.py that expect list rather then iterator. I am guessing this library should implement custom Pagination to properly process lists

@ola-t Hi, Ola! Could you provide the source code of your ModelViewSet, DocumentSerializer and Document with all the imports? I want to reproduce the issue.
