[FLINK-3185] [runtime, tests] Log error on failure during recovery
A failure during job recovery was not logged by the future executing the
recovery. This led a user to think that recovery was not happening at all.
Furthermore, some log messages have been improved and a test was fixed,
which was not failing, but only printing the stack trace on failures.

> Project: Flink
> Issue Type: Bug
> Components: Distributed Runtime
> Affects Versions: 0.10.1
> Reporter: Ufuk Celebi
> Assignee: Ufuk Celebi
> Fix For: 0.10.2
>
>
> If there is a failure during job graph recovery from ZooKeeper and the
> configured state backend, there is no way of telling what happened, because
> the operation happens in a future and does not log any exceptions.
> The user sees "Recovering all jobs" and after that no relevant log messages
> follow.
