Missing policy 's subjects after upgrading from OpenAM 11 to OpenAM 13.5

Test case

#1. Install OpenAM 11.0.3
#2. Create a new simple policy that include subjects with type Authenticated Users. Ensure that your rule name does not contain forward slash

#3. upgrade to OpenAM 13.5.0
#4. restart OpenAM 13.5.0
#5. login to OpenAM 13.5.0

#6. Notice that some odd Policy sets eg calendar, im, paycheck are created. ( See attachment : odd-policy-sets )

#7. verify your policy 's subjects. It is empty. ( see attachment : missing-subjects-info )

This issue can be workaround if you upgrade from OpenAM 11 to OpenAM 13 and then to OpenAM 13.5 again. Those odd policy sets will not be present too.
