What problem does this PR solve?

Issue Number: close #18456

Do the test in #18456, this will block 90s(2*lease), and it means OwnerCheckAllVersions returns "context deadline exceeded". And this problem will happen on unistore, not on TiKV.
Screen Shot 2020-07-10 at 12 26 50

Problem Summary:
On unistore we use MockSchemaSyncer, we need to do MockSchemaSyncer.OwnerCheckAllVersions like schemaVersionSyncer.OwnerCheckAllVersions.
