fix: quick fix for create mv ut timeout

[yezizp2012]

What's changed and what's your intention?

As title, this happens because of stopping the mock compute service during checkpoint. The barrier manager will enter recovery mode. This PR is a quick fix on this test, and test_create_materialized_view is outdated which need refactor.
