sticky_ip_address is not assigned just after the deployment

[Nobuto Murata]

Assigning sticky ip address ends with no error in the debug log below. However the sticky ip address is not assigned actually in the output of `maas maas nodes list` just after the deployment.

Manually executing the command above after the deployment assigns the sticky address successfully.
