Review: Needs Fixing

phablet at ubuntu-phablet:~$ system-image-cli -i
current build number: 61
device name: krillin
channel: ubuntu-touch/ubuntu-rtm/14.09-proposed
last update: 2014-09-25 06:14:42
version version: 61
version ubuntu: 20140925
version device: 20140919-1b3e670
version custom: 1411084873

On major problem I found is that the powerd system state request is still available even after the call is completed.

Follows what I got when testing with latest changes from silo 10:
Before the call:
phablet at ubuntu-phablet:~$ powerd-cli list
powerd-cli: Running as user is not fully supported.
System State Requests:
  Name: com.canonical.Unity.Screen, Owner: :1.15, State: 1

During the call:
phablet at ubuntu-phablet:~$ powerd-cli list
powerd-cli: Running as user is not fully supported.
System State Requests:
  Name: telepathy-ofono, Owner: :1.49, State: 2
  Name: com.canonical.Unity.Screen, Owner: :1.15, State: 1

After the call:
powerd-cli: Running as user is not fully supported.
System State Requests:
  Name: com.canonical.Unity.Screen, Owner: :1.15, State: 1
  Name: telepathy-ofono, Owner: :1.49, State: 1
phablet at ubuntu-phablet:~$ powerd-cli list
powerd-cli: Running as user is not fully supported.
System State Requests:
  Name: telepathy-ofono, Owner: :1.49, State: 1

The main problem with this issue is that the device is never going to suspend until that remaining system state lock is released.
