docs: Add dir_id and restore_path to trashed docs (#2625)

Trashed documents not only have a new `trashed` attribute, they also
  have a `restore_path` attribute with their previous parent path and
  their `dir_id` is changed for the Cozy Trash special id.

  Although those are rather internal attributes, they can be useful when
  stubbing a response from the stack or a Cozy CouchDB record.
