VNC recording not working correctly if BrowserWebDriverContainer used as @ClassRule

The following test won't record any videos:

public class ChromeRecordingWebDriverContainerClassRuleTest extends BaseWebDriverContainerTest {

    @ClassRule
    public static BrowserWebDriverContainer chrome = new BrowserWebDriverContainer()
        .withDesiredCapabilities(DesiredCapabilities.chrome())
        .withRecordingMode(RECORD_FAILING, new File("./build/"))
        .withRecordingFileFactory(new DefaultRecordingFileFactory());

    @Test
    public void recordingTestThatShouldBeRecordedButDeleted() {
        doSimpleExplore(chrome);
    }

    @Test
    public void failingTest() {
        doSimpleExplore(chrome);
        assert false;
    }
}

If recording mode is set to RECORD_ALL, only a single file is created:
PASSED-ChromeRecordingWebDriverContainerClassRuleTest-null-20180523-095412.flv

If the container is used as @Rule with RECORD_ALL, the two expected files are created:
FAILED-ChromeRecordingWebDriverContainerClassRuleTest-failingTest-20180523-095506.flv
PASSED-ChromeRecordingWebDriverContainerClassRuleTest-recordingTestThatShouldBeRecordedButDeleted-20180523-095511.flv

ChromeRecordingWebDriverContainerClassRuleTest から始め、RECORD_ALL を使って @ClassRule と @Rule の違いを再現します。クラススコープのテストにおける BrowserWebDriverContainer の記録ライフサイクルと記録ファイルの命名を追跡します。各テストがテスト名を含む期待どおりの記録を生成すれば完了です。
