Title: Fix query for RoleImplications with a NULL source context

* SQL's `IN` operator never matches `NULL`, so implications from Role
assignments in the `null` context were not found and permissions were
missing (specifically, the implication from ProgramCreator ->
ObjectEditor was not happening).
