Using the ResourceURIResolver._resolve method, I try to resolve the uri of a resource located at : "/ametys:root/ametys:resources/......"
The ResourceURIResolver from the plugin web returns the following uri : "/null/_resources/......"
The expected uri should be : "/_resources/......"
This happens because the following line is executed when siteName is null :
result.append(_prefixHandler.getUriPrefix(siteName));
