Support boolean values in this.get()

Fixes issue #10

This will work for false, but not undefined or null. How about this instead?

let thisValue = {
  get(property) {
    if (property.includes('.')) {
      return get(changes, property) || get(content, property);
    }

    if (changes.hasOwnProperty(property)) {
      return get(changes, property);
    } else {
      return get(content, property);
    }
  }
};

If the property exists in changes, then return that. This way, it should work with undefined and null too. Otherwise, return the property from content.

I'm not sure how best to handle property paths (i.e. this.get('a.b')), so that might need some more thinking, hence the check for a dot in the first conditional.

This has just become an issue for us. Setting a property to null doesn't behave as you'd expect because it gets proxied to the model, which still has the value.

Hey @Henridv, sorry for the delay. I am back from vacation now. :)
