   Fix core bug of convert to predicate column
   
   ## Problem Summary:
   
   recurrent:
   When `enable_low_cardinality_optimize = true`, for the TPCH dataset, using 
the following SQL query will Core
   ```sql
   select count(*) from lineitem where l_comment = 'ously even exc';
   ```
   
   This SQL will trigger the execution of 
`ColumnDictionary::convert_to_predicate_column_if_dictionary`, and 
`res->reserve(_codes.size())` is problematic because the current 
`_codes.size()` is smaller than its reserve value, so inserting a value into 
`PredicateColumn` will Core.
