Setting Text style.color does not work on 1.1.0
| -------------------------------------------------------------------------------------------------
| Reporting a bug or issue
| -------------------------------------------------------------------------------------------------

**Expected behavior:**

Setting the `color` property inside `<Text>` style should change the color of the text

**Observed behavior:**

Text color remains `#000`

**How to reproduce:**

Run `examples/basic-example` and the color names and hex should be in black. 

This only happens on `react-sketchapp@1.1.0` on Sketch@>=50. This is not an issue on Sketch @<=49.

Furthermore, this is not an issue on Sketch@>=50 with `react-sketchapp@2.x.x`

**Sketch version:**

50.2

**Please attach screenshots, a zip file of your project, and/or a link to your github project**

```
    <Text name="Swatch Name" style={{ color: textColor(hex), fontWeight: 'bold' }}>
      {name}
    </Text>
    <Text name="Swatch Hex" style={{ color: textColor(hex) }}>
      {hex}
    </Text>
```
