[CARBONDATA-2606][Complex DataType Enhancements]Fix Null result if
projection column have null primitive column and struct
**Problem:**
In case if the actual value of the primitive data type is null, by
[PR#](https://github.com/apache/carbondata/pull/2489), we are moving all the
null values to the end of the collected row without considering the data type.
**Solution:**
Place null in the end of output iff the null value is of complex primitive
column.
