Steps to reproduce:
- Add a new form with one text field (First Name).
- Save the form.
- Export the form entries and check the exported xls. There is only one "First Name" column.
- Edit the form created, and change the field name (not label) to "Name".
- Export the form entries and check the exported xls.
Actual result: There is a single "First Name" column.
Expected result: Two columns named "First Name (FirstName)" and "First Name (Name)" should be displayed.
