bugfix: fix can not get update columns with database name

[sustly]

Ⅰ. Describe what this PR did

buildAfterImageSQL时，如果数据库链接是全称getUpdateColumns获取不到更新字段。
如果数据库链接，如update seata.test.info，其中seata为库名字，test是表名，如果更新语句为： update seata.test set seata.test.info = "test" where seata.test.id = 1，则getUpdateColumns返回值是一个空的list.
支持了更新如果是库名+表名+字段的sql

Ⅱ. Does this pull request fix one issue?

fixes #3395

Ⅲ. Why don't you add test cases (unit test/integration test)?

没有

Ⅳ. Describe how to verify it

1.4.1版本写库名，测试不通过，获取不了更新字段

fixes bug后，测试通过

Ⅴ. Special notes for reviews

没有

LGTM. Mysql And Oracle test passed, pgsql do not have this problem. You can remove the code in pgsql or not.
