IQ Bind results should not have a 'from' value.
Description
IQ bind requests are used to request a resource. As such, the entity making the request can not yet be aware of its full JID at the time that the request is made.
If the corresponding result has a 'from' value, this confuses many clients. IQ Bind results should not have a 'from' value.
