slaprunner: (importer) Skip to continue restauration if instance don't exist

  The webrunner user don't necessary uses webrunner to develop slapos,
  he can use webrunner to develop a new component, where instance is never
  created.

  If the software release don't instantiate instances, skip from continue and consider
  the restauration job done (data is copied, software is built).
