OracleBufferedStatement failure after CakePHP 3.7

CakePHP 3.7 refactored BufferedStatement to use StatementInterface instead of StatementDecorator:
cakephp/cakephp@35dcf38

This removes the protected variable _statement in favor of statement:
https://github.com/cakephp/cakephp/blob/1f6fd21ca27ffc88fa88506a400b94a809e29254/src/Database/Statement/BufferedStatement.php#L43

As a result, recent calls to fetch() will fail with:

Exception: Call to a member function fetch() on null in [vendor/cakedc/cakephp-oracle-driver/src/Database/Statement/OracleBufferedStatement.php, line 36]
2019-03-06 18:24:03 Error: [Error] Call to a member function fetch() on null in vendor/cakedc/cakephp-oracle-driver/src/Database/Statement/OracleBufferedStatement.php on line 36

Code at fault is minimally:

cakephp-oracle-driver/src/Database/Statement/OracleBufferedStatement.php

Line 36 in eb45c20

$record = $this->_statement->fetch($type);

and

cakephp-oracle-driver/src/Database/Statement/OracleBufferedStatement.php

Line 41 in eb45c20

$this->_statement->closeCursor();
