[CARBONDATA-2328][PreAggregate] Fixed table With alias Issue
Issue: Query with table alias is not fetching data from pre-aggregate
Problem: when table has alias all the attribute reference's qualifiers
will have alias name, but as data map is created without alias so expression
comparison is failing.
Solution: While comparing alias remove qualifiers and then compare
expressions
