[REG 5.10.1 -> 5.11.0 Beta] Compilation of .UI files does not write all necessary includes

Since updating to 5.11.0 beta from 5.10.1, the compilation of the .ui file is missing the include for QIcon.

The ui file includes the following code:

  <property name="windowIcon">
   <iconset resource="/../Icons/Icons.qrc">
    <normaloff>:/Icons/info.png</normaloff>:/Icons/info.png</iconset>
  </property>

However, on compilation of this file, it is no longer adding #include <QIcon> to top of the generated .h file and as such compilation fails.

I also got a similar result with another .ui file where it was missing an include to <QAction>.
