Don't set empty values for the default EmpathyHandler

This implies the following:
- have an empty default handler when the Dispatcher is used directly
  with the singleton
- autogenerate the name for the default handler
- set priv->filters in the handler to an empty GPtrArray in this case,
  as that can't be NULL.
