fix(mirror): Fix instance_id check for tables without (#8852)

# Which Problems Are Solved

Fixes 'column "instance_id" does not exist' errors from #8558.

# How the Problems Are Solved

The instanceClause / WHERE clause in the query for the respective tables
is excluded.

I have successfully created a mirror with this change.
