CreateIdentityWizard: Adapt makeCreateIdentityStep() to use the data of Step.ChooseCreateOrRestore
- This won't compile yet because I haven't adapted WebOfTrust.restoreOwnIdentity() to return an OwnIdentity object yet. I'm committing this nevertheless so it's easier to determine where I left off in case I run in front of a truck.
- Document whats missing in the relevant FIXME.
