Description

When mvcc test is finished, we check if there any outdated versions are left in cache and not cleaned by vacuum. If so, an exception is thrown. There are some tests with this problem:

• CacheMvccTransactionsTest.testCleanupWaitsForGet1
• CacheMvccTransactionsTest.testCleanupWaitsForGet3
• CacheMvccReplicatedSqlCoordinatorFailoverTest.testAccountsTxSql_SingleNode_CoordinatorFails_Persistence
• CacheMvccReplicatedSqlCoordinatorFailoverTest.testPutAllGetAll_ClientServer_Backups0_RestartCoordinator_SqlDml
