Determines if a shape is orphaned. A shape is considered "orphaned" if it should be backed by a ModelElement, but it is not. If a shape is determined to be "orphaned", it's OnOrphaned() method will be called, which will remove the shape with the base implementation. The base implementation consider a shape under following two cases "orphaned":

  1. It has a PresentationViewsSubject link out of it, but the Subject cannot be resolved.
  2. It is a connector that should be mapped to an element link, but the underlying link cannot be found. (We special-case connectors because its PresentationViewsSubject link is not serialized by default).
