The test has been crashing flakily recently.
1) It is creating a QGLWidget
2) It is stealing the QGLContext of that widget and moves it into a separate
thread.
3) In that secondary thread it makes the context current.
4) Meanwhile the QGLWidget itself may receive for example a resizeEvent or
other events and - since it assumes that it owns the context - attempts to
make it current.
5) Attempting to call makeCurrent() on a QGLContext that is in a different
thread than the current thread (via QObject thread affinity) will result
in a call to qFatal() and consequently the test aborts.
The conclusion from Simon Hausmann is that this test is testing a pattern from
Qt4 times that may or may not have worked back then. Nowadays with the Qt5
QOpenGL* API we do support this properly and there appears little sense testing
this.
Therefore remove the test altogether.
