Optimistic @Version is increased when update fails due MongoSocketOpenException

[michaldo]

Actual:
On save attempt @Version attribute is increased. When save fails due MongoSocketOpenException, @Version attribute is not restored
As result, when socket connection is back, save fails due OptimisticLockingFailureException

Expected:
when save fails, @Version attribute should be restored. When socket connection is back, save should succeeded.

If you'd like us to spend some time investigating, please take the time to provide a complete minimal sample (something that we can unzip or git clone, build, and deploy) that reproduces the problem.
