invoke src parced incorrectly

If you refer file in invoke like:

<invoke src="subchart.scxml" autoforward="true"/>

then you get error like this:
 

error: src attribute resolves to non existing file (qrc:/subchart.scxml)

,but file exists. Same with files from disk.

Error is in http://code.qt.io/cgit/qt/qtscxml.git/tree/src/scxml/qscxmlcompiler.cpp?h=v5.9.1#n2441
