API doesn't sort resources

[giohappy]

The resources endpoint doesn't respect the sorting criteria requested in the GET parameters.
To be investigated if this also affects downstream APIs (datasets, documents, etc.).

Example request:
https://development.demo.geonode.org/api/v2/resources?include[]=executions&filter{metadata_only}=false&page=1&page_size=24&**sort=title**

The expected response is resources sorted by title, but it doesn't work.

It seems the issue is client side GeoNode/geonode-mapstore-client#1551

[giohappy]

Actually, this is not completed since it's marked also for 4.1.x, while it's been fixed only for master.
We will need to check if we can backport GeoNode/geonode-mapstore-client#1552 easily. I think so...

[giohappy]

Well, this can be closed in any case, since this issue is managed in GeoNode/geonode-mapstore-client#1551
The backport has been merged.
