[CARBONDATA-3028][32k] Fix bugs in spark file format table with multiple
longstringcolumns
If we create a spark file format table with multiple longstringcolumns
and the option long_string_columns contains blank characters, the
query on that table will fail, cause it didn't recognize the correct
varchar columns. The root cause is that carbondata didn't trim the blank
in long_string_columns while it recognizing the varchar columns.

your contribution quickly and easily:
