Disable checkbox for Preimage on step of type `create` to avoid exception

[imranakram]

When we try to register an pre-image on a step based on "Create" message, the system fails by giving an exception with a message: Message Create does not support this image type. Disable the checkbox instead and show this as a message on tool tip.

`Unhandled Exception: System.ServiceModel.FaultException

Message Create does not support this image type.
