xpath engine: change raise_for_httperror to no_result_for_http_status

Browse source 
no_result_for_http_status contains a list of HTTP status.
These HTTP status are seen an empty result list.
In other cases an exception is thrown as usual.

Previously raise_for_httperror were ignoring all HTTP error,
which make defective engines invisible in the stats.
