Add unit tests (#2235)

* Add Unit Tests for the following classes:

com.alibaba.otter.canal.client.adapter.support.JdbcTypeUtilTest
com.alibaba.otter.canal.client.adapter.support.UtilTest
com.taobao.tddl.dbsync.binlog.JsonConversion_Json_ValueTest
com.taobao.tddl.dbsync.binlog.JsonDiffConversionTest
com.taobao.tddl.dbsync.binlog.LogBufferTest
com.taobao.tddl.dbsync.binlog.LogEventTest
com.taobao.tddl.dbsync.binlog.event.LogHeaderTest
com.taobao.tddl.dbsync.binlog.event.RowsLogBufferTest
com.alibaba.otter.canal.parse.driver.mysql.packets.client.RegisterSlaveCommandPacketTest
com.alibaba.otter.canal.parse.driver.mysql.utils.ByteHelperTest
com.alibaba.otter.canal.parse.inbound.mysql.ddl.DdlResultTest
com.alibaba.otter.canal.parse.inbound.mysql.ddl.DruidDdlParserTest

These tests were written using Diffblue Cover

* Add dependencies and refactor
