Legend stroke color does not match mark config

[marcprux]

In this example, the fill color of the legend matches the mark's config, but the stroke color does not.

{
  "data": {"url": "data/cars.json"},
  "mark": "point",
  "config": { "mark": { "fill": "red", "stroke": "green", "color": "blue", "strokeWidth": 5 }},
  "encoding": {
    "x": {"field": "Horsepower", "type": "quantitative", "aggregate": "average"},
    "y": {"field": "Miles_per_Gallon", "type": "quantitative", "aggregate": "average"},
    "size": {"field": "Acceleration", "type": "quantitative"}
  }
}

Ha, I think this is a case where we use an if then else rather than two ifs.
