GeoNode Geoserver has an invalid generic style

[kikislater]

Expected Behavior

Geoserver has a valid generic style allowing uploading from geoserver itself and viewing with OpenLayers geoserver viewer

Actual Behavior

Empty generic style causing invalid wms rendering
Geoserver has an invalid generic style causing problems when uploading from geoserver itself (GUI or API : Geoflow for example). Could be shown in embeded Geoserver's OpenLayers or invalid WMS answer.

Steps to Reproduce the Problem

1. Log in to geoserver admin
2. Go to style => generic
3. Invalid style

I confirm the generic.sld file is empty inside the default GeoNode-GeoServer DATADIR

Created upstream issue GeoNode/geoserver-geonode-ext#124

[kikislater]

It happens since Geonode 2.8 and Geoserver data > 2.10 : https://build.geo-solutions.it/geonode/geoserver/latest/data-2.14.x.zip

[giohappy]

fixed in GeoNode/geoserver-geonode-ext#124
