    [HOTFIX] Fixed NPE during query with Local Dictionary
    
    Problem:
    Query is failing with NPE when some blocklet encoded with local dictionary and some without local dictionary.
    Root Cause:
    This is coming because in carbonvectorProxy setDictionary with null it is not setting the dictionary to null because of this it is treated like a local dictionary column but column is not encoded with dictionary.
    Solution:
    Set dictionary to null
    
    This closes #3068
