COMP: Remove unnecessary includes in vtkMRMLAbstractLogic header

This has the side effect of having a faster compilation

External module OpenIGTLinkIF and MultiVolumeExplorer have already been
updated according to change in vtkMRMLAbstractLogic header.
See #3493 / r22712  and  #3494 / r22693

On the other hand, no test build have been done for the extension. Issue
will be resolved on case by case following the dashboard results.
