BUG: Wrong FatalIOError message in displacementMethod and optMeshMovement

- The core of the FatalIOError message was not printed due to exiting
  with FatalError instead of FatalIOError
- Changed the TypeName in all derived classes of displacementMethod so
  that the toc printed by the FatalIOError corresponds to what the user
  should add in dynamicMeshDict
