server: don't convert failure in errback to jsonrpclib.Fault anymore:
failure in bridgeCall was always converted to jsonrpclib.Fault, resulting in loss of useful debugging data.
This conversion as been modified to the signal handler which is only used by Libervia Legacy.
Note that txJsonRPC will be totally removed for 0.8 release.
