[SPARK-18337] Complete mode memory sinks should be able to recover from
checkpoints
## What changes were proposed in this pull request?
It would be nice if memory sinks can also recover from checkpoints. For
correctness reasons, the only time we should support it is in `Complete`
OutputMode. We can support this in CompleteMode, because the output of the
StateStore is already persisted in the checkpoint directory.
## How was this patch tested?
Unit test
