In 3.1.3 `umaGrantAccessIfNoPolicies: true`, in 3.1.4 `umaGrantAccessIfNoPolicies: false`.
This is the reason why it starts to fail in 3.1.4. We changed default value to `false` to force admin chose between two options:
* specify UMA RPT Policy that protects resource to which request is performed
* set `umaGrantAccessIfNoPolicies: true` manually and confirm that it is ok that UMA Resource is not protected by any policy, making it open for anyone.
