Mahmood Ali e0da3c5d0e rename to hasLocalState, and ignore clientstate
The ClientState being pending isn't a good criteria; as an alloc may
have been updated in-place before it was completed.

Also, updated the logic so we only check for task states.  If an alloc
has deployment state but no persisted tasks at all, restore will still
fail.
