Kari Oikarinen d42a9d19ff Remove tst_QGLThreads::textureUploadInThread
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.
