Review Comment:
so, I use debug mode to check the unit test, I found that
`listTableDescriptors` is always using the `cache` of `FSTableDescriptors`
instead of loading from the filesystem, such that we're relying on the
`tableStateManager` via meta to see if the additional loaded tables should be
included.
the test itself is right, just I'm wondered practically how newly added
table on the primary/write cluster being added to the `cache` of
`FSTableDescriptors` after master has been initialized ? or does it add from
the filesystem after restarting the master (meta is yet synced)?
