Describe the bug
Nacos 3.0.0-Beta run with derby database failed, due to execute SQL failed:

SELECT COUNT(DISTINCT ci1.data_id, ci1.group_id) AS count FROM config_info ci1 WHERE ci1.tenant_id = 'public' AND (ci1.src_user <> ? OR ci1.src_user IS NULL) AND EXISTS (SELECT 1 FROM config_info ci2 WHERE ci2.data_id = ci1.data_id AND ci2.group_id = ci1.group_id AND ci2.tenant_id = '' AND (ci2.src_user <> ? OR ci2.src_user IS NULL))

The error message is sql parse failed in 1:34, which means the , of DISTINCT ci1.data_id, ci1.group_id.

And I try to close the migrate of namespace by failed.

I see the ConfigCompatibleConfig class without reset in constructor.
