Description

Mapstore currently fails to parse the GetCapabilities result that contains inspire_vs:ExtendedCapabilities for retrieving styles.
it fails here and it goes then in the catch here

I also noticed a variety of ways to retrieve & parse getCapabilities we should unify
https://github.com/geosolutions-it/MapStore2/blob/master/web/client/actions/layerCapabilities.js#L55
https://github.com/geosolutions-it/MapStore2/blob/master/web/client/api/WMS.js#L113
https://github.com/geosolutions-it/MapStore2/blob/master/web/client/api/WMS.js#L169
https://github.com/geosolutions-it/MapStore2/blob/master/web/client/observables/wms.js#L42

How to reproduce

• open map with id 451 map
• open TOC
• select layer temperatura
• open layer settings
• check debugging the notified points

Expected Result

to see the styles for that layer

Current Result

there is this error when parsing with jsonix

"Element [{http://inspire.ec.europa.eu/schemas/inspire_vs/1.0}inspire_vs:ExtendedCapabilities] 
could not be unmarshalled as is not known in this context and the property does not allow DOM content."

so the styles list is empty
