GBP: Resource intergrity fails between policy-rule-set & external-policy

[puppet-py]

If a policy-rule-set is created and in turn consumed/provided by an External-Policy, then we allow the deletion of the in-use Policy-Rule-Sets.
Expectation: The deletion of the in-use Policy-Rule-Set should fail

Please find the sequence of execution below:
