Build Identifier: 4.0

Scenario:
1. Offline clone commits via WritheThroughCommitContext to the master repository (commit A).
2. A session on the master repository commits changes (commit B) which depend on the commit A.
3. The offline clone writes commit A to the store.
4. The offline clone receives an CDOSessionInvalidationEvent of commit B and put it to the local store.

Under certain circumstances 4. can be executed before 3. (E.g. commit A is huge and commit B is very small).

The following execption is then thrown: 
[ERROR] Failed to register revision: Tracker@OID1746:0v130

Because the store alreay contains a newer object (from commit B) than the one from commit A.


Reproducible: Sometimes
