[JUnit StatusBar] Shows wrong progress information when the same test is executed multiple times

[rherrmann]

Even though this is a weird test suite setup, I've seen this in the wild:

@RunWith(Suite.class)
@SuiteClasses({ SubTestSuite.class, FooTest.class })
public class MasterTestSuite {
}

@RunWith(Suite.class)
@SuiteClasses({ FooTest.class })
public class SubTestSuite {

}

public class FooTest {
    @Test
    public void testSomething() {
        fail("Not yet implemented");
    }
}

Running the MasterTestSuite will execute testSomething twice. The JUnit progress meter, however, will show 1 / 2, indicating the one of two tests have been executed.
