Race condition when spreading ...SlugField before a group of tabs

[ItsChrisHickman]

Error - (name was defined) when used within a collection containing tabs. Solution is to spread the SlugField -after- the tab group.

fields: [
    {
      name: 'name',
      type: 'text',
      required: true,
    },
    ...SlugField('name')
    {
      type: 'tabs',
      tabs: [
        {
          label: 'Foo',
          fields: [
            {
              name: 'bar',
              type: 'text',
            },
        }
     ]
  }
