[CARBONDATA-2998] Refresh column schema for old store(before V3) for
SORT_COLUMNS option
**Problem:**
For old store, store before V3, SORT_COLUMN option is not set in
ColumnSchema, but considered as SORT_COLUMNS. So, while refreshing the table it
will try to read from the thrift and make it as no sort column in ColumnSchema
as it is not set before.
**Solution:**
While refreshing the table, check for the SORT_COLUMN property in the table
properties and if nothing is set, then by default take all the dimension
columns as SORT_COLUMNS.
