[CARBONDATA-3004][32k] Fix bugs in writing dataframe to carbon with longstring Currently while writing dataframe to carbon table, we need to parse the rows in dataframe. For string columns, we need to judge whether it is a long string column or not. In current implementation, the judgement is position based which means that the order of fields in dataframe should be the same as that in create table. In this PR, we fix this bug. This closes #2812
