Remove unstable test from qgraphicsscene test.

The removed test was disabled in February 2007 because it did not work
cross-platform.  The comment that was added at the time claims that the
functionality is covered thoroughly by other tests, but even if that
isn't true we're not losing anything by removing this test as it is not
even useful as a starting-point for a new test due to its reliance on
random test data.
