Bug description:
  For example:

  tim@ubuntu:~/dev/ubuntu-ui-toolkit/m/headerAnimate/tests/unit_x11/tst_components$ GRID_UNIT_PX=16 ../../../ubuntu-ui-toolkit-launcher/ubuntu-ui-toolkit-launcher tst_pagehead_visible.qml 
  file:///usr/lib/x86_64-linux-gnu/qt5/qml/QtTest/TestCase.qml:337:32: Unable to assign [undefined] to bool
  [PERFORMANCE]: Last frame took 124 ms to render.

  and other test files,
  <kalikiana> timp: these show on tst_adaptivepagelayout_configuration.qml as well

  I suspect they come from ucpagetreenode, that's why I assign the bug
  to Benjamin.
