By moving the refresh code into the method used for getting sending queue entity for the old model object
we want to make our code better protected from working with inconsistent sending queue data.

In case we save the task and and queue saving fails the sending may be triggered with incorrect data in the queue.
Since the scheduled task is used for controlling sending state lets save it as last so that we are sure all related
data are up to date before saving the task.
