Pedigree editor does not prompt for save if patient is added to an existing family and left unliked
Description
This anomaly is present in master as of July 4,2018.
create new patient
open pedigree editor and chose an existing family
close pedigree
nothing happens; the patient isn't added to the family (expected behaviour is to prompt the user to save/cancel their changes)
: NOTE for release notes: this behaviour is caused by a combination of other changes done for 1.4RC1, a similar problem may exists in 1.4m4 but in a different form, namely something covered by PT-3718. So release notes should only explicitly mention in pedigree section
Environment
None
