[FLINK-3390] [runtime, tests] Restore savepoint on ExecutionGraph restart
Temporary work around to restore initial state on failure during recovery as
required by a user. Will be superseded by FLINK-3397 with better handling of
checkpoint and savepoint restoring.
A failure during recovery resulted in restarting a job without its savepoint
state. This temporary work around makes sure that if the savepoint
coordinator
ever restored a savepoint and there was no checkpoint after the savepoint,
the savepoint state will be restored again.
