databases/cego: update 2.39.5 -> 2.39.7

• Fix in CegoTableManager::deleteDataTable, pBlock has to be checked for null value, otherwise crash recovery might crash. ( bug came with 2.39.0 to check for pBlock->getTriggerValueList )
• Some clob related fixes in CegoQueryHelper::decodeNativeFVL / decodeFVL relevant for recovery handling
• Fix in CegoRecoveryManager::recoverCurrentTransactionLog for the INSERT case. For the blob/clob handling, the lobREf values have not been set up correctly. This might lead to problems for table recovery with more than one lob row ( e.g. table t1 ( a blob , b clob )
