### What problem does this PR solve?
The materialized view is created based on external table, and sometimes
refreshing the materialized view may report that the corresponding
partition cannot be found.
The reason is that when the materialized view is refreshed, predicates
are generated based on the refreshed partition, and the problematic plan
does not include predicates.
The code for adding predicates is as follows:
```
if (predicates.getPredicates().containsKey(table)) {
return new LogicalFilter<>(ImmutableSet.of(ExpressionUtils.or(predicates.getPredicates().get(table))),
unboundRelation);
}
```
If the table and predicates. get() are not the same object when setting
predicates, it will not be obtained, resulting in the absence of
predicates
PS: The table cache will refresh within 24 hours by default, and the
objects will change
