This pull request fixes #5768

Describe Your Solution 🔧

Currently all UT have a ShowNamespace command and wrapped by ObjectFilterPlaceHolder

And ObjectFilterPlaceHolder such command will go through buildQuery(), it's noisy when dev to debug and unnecessary, we should just skip it since we have check privilege when executing.
