Call pyuno.private_initTestEnvironment() only once

...instead of once for each class derived from CollectionsTestBase (as listed in
pyuno/PythonTest_pyuno_pytests_testcollections.mk), causing the

  assert(!pSVData->maDeInitHook.IsSet());

in Application::setDeInitHook (vcl/source/app/svapp.cxx) to fire.

This is probably far from being idiomatic Python code...
