openstack-config always applies oldest config change

Related to: https://blueprints.launchpad.net/fuel/+spec/openstack-config-change

Environment:
1)ISO fuel-8.0-284-2015-12-10_19-42-00.iso
2) Controller+Compute

Description: I'm doing nova.conf changes with "fuel openstack-config". I've found that latest uploaded change is not applied,
but Fuel applies initial (oldest) change.

Steps to reproduce:
1) Deploy environment (Controller+Compute)
2) fuel openstack-config --upload --env 1 --node 2 --file config-controller.yaml
3) fuel openstack-config --execute --env 1 --node 2
4) Check that controller's nova.conf has "anyitem=True"
5) fuel openstack-config --upload --env 1 --node 2 --file config-controller2.yaml
6) fuel openstack-config --execute --env 1 --node 2

Expected result:
nova.conf on node-2(controller) has "anyitem=CORRECTEDVALUE"

Actual result:
nova.conf on node-2(controller) has "anyitem=True"

Details:
config-controller.yaml:
---
 configuration:
   nova_config:
     DEFAULT/anyitem:
       value: True

config-controller2.yaml:
---
 configuration:
   nova_config:
     DEFAULT/anyitem:
       value: CORRECTEDVALUE
