### What changes were proposed in this pull request?
Temporary apply the `HiveSubQueryRemoveRule` before collecting tables
scanned by the initial CBO plan when performing sql text based MV rewrite.
### Why are the changes needed?
For Materialized View rewrite based on exact sql text match Hive uses the
initial CBO plan which may contains sub-query expressions but the algorithm
traverse the plan and collects the tables can not handle sub-query expressions.
### Does this PR introduce _any_ user-facing change?
Yes. If a query plan was rewritten to scan an outdated MV the results can be
different.
### How was this patch tested?
