Fix database connection leak when closing PDO connection
We discovered a resource leak (database connection leak) in our application's test suite. We investigated and discovered that, although the test suite was calling `CI_DB_driver::close()` after each test, the `result_id` member variable still maintained an internal reference to the database connection, which kept the connection from being closed. This is using pdo_sqlsrv; I have not tested other PDO drivers. Signed-off-by: Josh Kelley <joshkel@gmail.com>
