Relationships created by Use Household Address, Add to Household and Add to Organization are DISABLED when created

When CRM_Contact_BAO_Relationship::add() is invoked from Contact_Form_Individual::handleSharedRelation() and from AddtoHousehold and AddtoOrganization postProcess() - we now need to explicitly include is_active = 1 in the params. Currently, we don't do this and the relationships are created with is_active = 0.

This was caused by a changed in the add() function. I've grep'd for all instances of that method and only found the three noted above.
