[CARBONDATA-1145] Fix single-pass issue for multi-task loading
**Issue**
The single-pass loading of partition table lost incremental dictionary. The
query result of dictionary column is null.
**Analyze**
During the single-pass loading, the executor will send many initial message
to server to initialize the dictionary generator. for each initial message, it
will update the generator, will lead to lost some incremental dictionary.
**Solution**
Reuse the dictionary generator, no need to update it if exists.
