Setting a value to a property of a child item does not work.

Setting a value to a property of a child item does not work when child is a property of a parent.

Ways to reproduce:

1) Build the attached project with Qt for MCU 1.8.0
2) Build gives the following error: CMakeFiles\qtmcu39.dir\qtmcu39.cpp(37): error C2039: 'number': is not a member of 'Qul::Property<MySubType *>'

qmltocpp generator fails to generate the code properly. It handles the property instead of value of property.
Minimal change to qmltocpp output fixes the problem.
