When accepting an invitation for a "family" type of study with a father and a mother, we get the

exception when trying to deploy it.

This is a "normal" exception/behavior, since not all devices have been registered. In this case, I am the "father" but the "mother" has not registered yet, so I can't deploy my study.

But - this is not working in practice, since in this way, no devices will ever get registered.

We need to separate the registration of devices from deployment in the study app.
