Add sleep before trying to cancel pending restore.

We have encountered situations that indicates that the server responds:
"There are no restartable restore sessions."
But in the following command says:
>>>>>> Restore Processing Interrupted!! <<<<<<
ANS1330S This node currently has a pending restartable restore session.

The requested operation cannot complete until this session either
completes or is canceled.
