ValueProvider with default value fails using DirectRunner

 The bug is shown by the following short piece of code. 
```

public class ShowProblem implements Serializable {
  public interface MyOptions
extends
PipelineOptions, DataflowPipelineOptions {
      @Description("OutputFile")
      @Default.String("gs://xyzzy/helloWorld")
 
    ValueProvider getOutput();
      void setOutput(ValueProvider value);
    }
 
public static void main(String args[]) {
    MyOptions options =  PipelineOptionsFactory.fromArgs(args)  
            .as(MyOptions.class);
    Pipeline pipeline = Pipeline.create(options);
    pipeline
 
      .apply(Create.of("hello", "world", "!"))
        .apply(TextIO.write().to(options.getOutput()));
 
  pipeline.run();
  }
}

```

 If this pipeline is run with the "–output=gs://xyzzy/myfile" option, it runs fine both locally and on Google.  If this pipeline is run without the \--option, it runs fine on Google, but fails when run locally.

When given an output argument, the ValueProvider returned by getOutput() is a StaticValueProvider; when using the default value returns a RuntimeValueProvider,   The latter seems to have a bug hinted at in the comment just above RuntimeValueProvider.get().  The code expects that when running the pipeline (and only when running the pipeline), someone has already called
```

RuntimeValueProvider.setRuntimeOptions(options)
```

There is apparently no call to this method when using a DirectRunner.
