Unexpected session flush when calling AuditReader.GetCurrentRevision

[akonit]

Hello

There is a problem when calling AuditReader().GetCurrentRevision(true) - it leads to immediate flush of uncommited session data. If calling GetCurrentRevision with persist = false, then problem is gone. It seems, that unexpected flush happens when saving revisionData by DefaultRevisionInfoGenerator.

I made a PR to illustrate the problem: #21
