The 'stroke' outline for each dataset is missing

Steps to produce the issue

If you start with https://carbon-design-system.github.io/carbon-charts/?path=/story/area--stacked-area-time-series … and you change “date” to “key” ( eg: https://codesandbox.io/s/cranky-payne-9yxq3?file=/src/index.js ) the ‘stroke’ outline for each dataset disappears

@natashadecoste could you please look into this issue?

I found a similar issue that I think is related to this bug as well. In the SimpleBarChart story, if you replace the data with this:

[
  {
    "key": "Qty", // Notice the "key"
    "value": 65000
  }
]

It crashes the chart.

Let me know if I should open a separate issue for this.

this should have been fixed with #678
