Steps to reproduce the problem on the master branch after the merge of PT-3402:
log in as Alice
create a new patient
draw a pedigree
make the patient open
log in as Bob: Bob can edit the patient, but cannot see the pedigree or that the patient has a family
bug: Bob can start drawing a new pedigree, with a new family, but when trying to save an error is displayed: "Unable to save pedigree: Patient P123 already belongs to a different family FAM123, and therefore can not be added to this one"
Bob should not have the option to draw a pedigree in this case, but there should be a warning message, for example "This patient belongs to an undisclosed family".
