While using the pageInfo hasPreviousPage and hasNextPage cursor based navigation (before and after), it seems these results are always set to False.

The corresponding code (https://github.com/graphql-python/graphql-relay-py/blob/master/graphql_relay/connection/arrayconnection.py#L104-L105):

return connection_type(
    edges=edges,
    page_info=pageinfo_type(
        start_cursor=first_edge_cursor,
        end_cursor=last_edge_cursor,
        has_previous_page=isinstance(last, int) and start_offset > lower_bound,
        has_next_page=isinstance(first, int) and end_offset < upper_bound
    )
)

Querying with first: 5, after: "xxx" in this case always results in hasPreviousPage: false.
The same for last: 5, before: "xxx", which results always in hasNextPage: false.
