Smita Kulkarni c846720f3d Fix for qualified asterisks with alias table name and column transformer 
Implementation:
* Removed check that qualified asterisks should have only 1 child. It can have more than 1 children when the rest of the children are column transformers. Added check for the same.
* Updated ExtractAsterisksMatcher data to store table name and table alias name as both can be referenced in the query.
Testing:
* Added a test 02518_qualified_asterisks_alias_table_name.sql
