Wrong handle with null values on getRemoteStatus

Here the patch to add the nullable string.

Using a different approach.

Instead of using null, widget_ingestion module will set the status to the new unknown whenever the status is not set in the registry.

The default value for the field remote_widget_status inside the customBaseFieldDefinitions is also set to unknown.

Also, I've fixed one typo.

I love this.
