Usage of 'default()' callback on fields does not work

[garrettmassey1]

If your field uses the default() callback on any of the standard Nova fields, the callback either is not called or is not rendered properly because the resulting field on the view is not populated with any default values.

I was able to get it to work by replacing the resolvePanel() method in the SettingsController with the following:

    private function resolvePanel(Panel $panel, $values, NovaRequest $request)
    {
        return collect($panel->data)
            ->each(function (Field $field) use ($values, $request) {
                $value = $values[$field->attribute] ?? null;

                // Resolve the value for the field
                $field->resolve($this->makeFakeResource($field->attribute, $value));

                // Apply default if no value exists
                if (is_null($value)) {
                    $field->resolve(
                        $this->makeFakeResource(
                            $field->attribute,
                            $field->resolveDefaultCallback($request)
                        )
                    );
                }
            })
            ->toArray();
    }

But I have not tested it beyond text fields and boolean fields / boolean group fields.
