Storybook: Vue stories don't work with mixins

[Jivanvl]

Describe the bug
A clear and concise description of what the bug is.

To Reproduce
Steps to reproduce the behavior:

1. Go to http://jivl-mixin-storybook-bug.162.243.131.170.nip.io/?path=/story/charts-stacked-column-chart--with-toolbox
2. Click on Show Toolbox
3. See error

Expected behavior
Show Toolbox should show a toolbox on top of the chart, that property comes from a mixin, it seems to me that the mixin prevents the property from receiving the values correctly, see attached screenshot

knobs values must be passed in as prop default values. (this was a change done somewhere in sb 4.x, but not very well documented):

add('My Story', () => ({
  props: {
    showToolbar: { default: boolean('Show Toolbar', false) }
  }
}))
