function DatabaseExceptionWrapperTest::testPrepareStatementFailOnPreparation

Tests Connection::prepareStatement exceptions on preparation.

Core database drivers use PDO emulated statements or the StatementPrefetch class, which defer the statement check to the moment of the execution. In order to test a failure at preparation time, we have to force the connection not to emulate statement preparation. Still, this is only valid for the MySql driver.
