Failure of read database policy for related entity in multiple create for N:1 and 1:1 relationships returns error

Start by reproducing a multiple-create operation involving N:1 or 1:1 relationships with a restrictive read policy on the related entity. Trace how the insertion result is handled when the policy prevents returning it; done means the operation no longer raises the reported exception and the read policy remains enforced.
