My valgrind got slower, it seems :-)
Add a T__RequestServerVersion header to the EWS unittest
Clean up generated code from setNamespaceUri(QLatin1String("")) lines.
defaultQualified is actually different for elements and attributes.

See elementFormDefault="qualified" vs attributeFormDefault="qualified".
* Write out attribute namespace, if attribute is qualified, or ns differs from parent element

* Set the namespace on attributes, the same way it was done for elements.

These two changes need to go in together, otherwise wsdl_document regresses.

That test was changed to use attributeFormDefault="qualified" since
msexchange_wsdl tests the other case (attributes are not qualified)
