Importing geojson into geogig repo causes rendering/projection issues

[smesdaghi]

to reproduce:

• upload a shape file, and view in maploom for verification
• in geonode layer detail page, select download layer, download as geojson
• rename the downloaded geojson file to a unique file/layername not in geoserver / geonode
• upload the layer as ususal into the default geonode_imports postgis data store
• verify upload succeeded and data renders properly in maploom
• rename the geojson that was downloaded to a new unique file name
• upload the geojson file into a geogig repo
• when it complete, not that zoom to data of the layer in maploom will take you to where the data is which is not where original data was.
