Expand QueueModel tests

[eLopez6]

There are too few tests for QueueModelTest. And we need to test more behavior.

Running into an exception when attempting to running the old test suite.

This some stuff that I'm lost on how to use correctly:

From setupClass()

    	// Ensure that there are no existing library files
    	Main.resource.getResourceFileClass("test_out>QueueModelTest>library", App.class).create().delete();

        settings = new SettingsModel(Main.resource.getResourceFileClass("settings.ser", App.class));
        library = new LibraryModel(settings, Main.resource.getResourceFolderClass("test_out>QueueModelTest>library", App.class));

And from setup

        Main.resource.getResourceFileClass("test_out>QueueModelTest>test_meta.ser", App.class).create().delete();

        testAudio = new BAudioLocal(settings,
                                    Main.resource.getResourceFileClass("test_out>QueueModelTest>test_meta.ser", App.class),
                                    Main.resource.getResourceFileClass("test_in>test.mp3", App.class).getPath().toUri());
        queueModel.setQueue(library, testAudio);

So it seems like to me, the creation of the BAudioLocal should be associating it with the test meta info. But when I look at the loaded queue in a debugger, I don't think I see it.

And more detail again: I get an IndexOutOfBoundsException on queue.get(), which would mean the audio file created is not actually in the queue. Or maybe library.

I've written some skeleton-ish code for this. Definitely not as implemented as I would like to be. But the QueueModel is a little more complicated to write tests for than I realized given the resource folder issue that Kienan is working on.
