Families shared with me are missing some families with shared patients

To reproduce the problem:

• two user accounts Mary and Peter

• Peter created a patient and gives Mary all rights as collaborator (view, edit, permissions)

• Mary creates a family with patient above in its pedigree

• Mary sees the newly created family as her own

• Peter does not see the family on the landing page (problem)

• Peter can see this family if he goes to the Browse all families, where he can change the family, but not delete it (correct).
