No regOps.getErrorMessage() when trying to perform registration when no registration is loaded

[mfizyczka]

I simply forgot to create a new registration and no registration was loaded, I used this lines:

rigidRegistrationSettings = velocity.DefaultRigidRegistrationSettings()
orThrow(regOps.performRigidRegistrationDICOM(rigidRegistrationSettings), regOps)

I did a bit of debugging here as there was no error message, no exception, script just stopped working without. It took me a quite some to find out the silly mistake. Would be nice if you could add catching this type of Error.

Thank you for finding this, we will try to address this in the next build.
