Description
JDBCSuite and JDBCWriterSuite have its own testH2Dialect for their testing purposes.
This issue fixes testH2Dialect in JDBCWriterSuite by removing getCatalystType implementation in order to return correct types. Currently, it returns Some(StringType) incorrectly. For the testH2Dialect in JDBCSuite, it's intentional because of the test case Remap types via JdbcDialects.
