Test annotations on GeoNode 3.3.x

[giohappy]

@ElenaGallo please create a test (if it doesn't exist) for annotations both on 3.3.xs and master, and execute it.
In particular check that this issue is solved GeoNode/geonode-mapstore-client#484

@giohappy I added a test, on cucumber, for annotation issues and it passed both 3.3.xs and master.
