Description:
------------
A client request can be "one way" or not, if "one way", an empty response will be given to the caller (__getLastResponse() returns empty string).

As i can see in soap.c (do_soap_call() : 2692), the "one way" detection is based on the wsdl : if the function (operation) has no "output message", no need to read the response, but in this case no faults will be taken in count.

I report it as a bug since there is no mention in the doc of the necessity for a function to return something to make SoapFault system work and __getLastResponse() work.

I first wanted to post it as a note in the doc but it says to not post bugs there.

Expected result:
----------------
__getLastResponse() returns the response and SoapFault's are thrown in the client

Actual result:
--------------
__getLastResponse() returns empty string and no SoapFault thrown in the client (SoapFault's are lost in nature)
