When we create several calculated dimensions in a table chart aggregated, Superset keep the last name given, and not the default value

How to reproduce the bug

1. Create table chart 'aggregated'
2. Create a dimension with custom_sql and Name it
3. Create another one
4. By default it keep the name of the previous column, and not the value by default
5. So the new column is not taken in account in the table, because they have the same name

Expected results

Always have the default value when we create a calculated dimension

Actual results

By default it keep the name of the previous column, and not the value by default
