    Trust unit tests should target additional threat scenarios
    
    This adds unit tests for two threat scenarios around the trust functionality
    that are not currently tested.
    
    The first scenario is related to deletion of a grant that has been previously
    delegated via a trust. We need to ensure that executing a trust for a role that
    the trustor no longer has is rejected.
    
    The second scenario is related to an attempt to use a trust token with
    impersonation to execute another trust as the impersonated user. We need to
    ensure that a trust token can't be used to execute another trust.
