for Detla, the test would break at the skipTestUnless(hasBehavior(SUPPORTS_MULTI_STATEMENT_WRITES)); because Delta doesn't support this. Only Hive does ATM, AFAIR.
Delta connector supports write in autocommit mode only, but it should allow multiple reads in a transaction (e.g. reading from Delta and writing to Hive connector). The commit removes the check from `DeltaLakeConnector` since appropriate check is being done in `InMemoryTransactionManager`.
