[SPARK-27690][SQL] Remove materialized views first in HiveClientImpl.reset

## What changes were proposed in this pull request?

We should remove materialized view first otherwise(note that Hive 3.1 could reproduce this issue):
```scala
Cause: org.apache.derby.shared.common.error.DerbySQLIntegrityConstraintViolationException: DELETE on table 'TBLS' caused a violation of foreign key constraint 'MV_TABLES_USED_FK2' for key (4).  The statement has been rolled back.
