0.12.1版有个bug，新建tags是可以用contains查询的，但服务重启后就没法再查询了


The report provides only a screenshot and describes a failure in tag contains queries after restarting IoTDB 0.12.1. Start by reproducing the sequence: create tags, query with contains, restart the service, and repeat the query. Trace the tag persistence and query entry points; done means the same contains query succeeds after restart.
