Log errors when loading stories on device fails

[micheleb]

Issue: I had a typo in a style definition for one of my components, and although everything worked fine on web, the React Native expo app would stop loading all my stories, without logging any error on the console.

What I did

I added a try / catch block around the loadable() function inside loadCsf.ts, so that any error that happens inside the configure() call (inside .ondevice/storybook.requires.js) gets logged.

How to test

• Add an invalid field (e.g., aspecRatio, with a missing t) to a style used by one of your components, and include it in a story
• Run expo start
• Launch storybook via expo on your device
• You should now get an error message in your console like:

  "aspecRatio" is not a valid style property.
  StyleSheet myStyle: {
    "aspecRatio": 1.5,
  }
  Valid style props: [
    "alignContent",
    "alignItems",
    ...```
