Download Members including terminated members inappropriately

[mkimberlin]

Describe the bug
"Download Members" CSV report ignores whether "Include terminated users" is checked and always includes terminated members. This is problematic because we cannot easily tell from the output who is active (termination date is not included in the report).

To Reproduce
Steps to reproduce the behavior:

1. As an Admin user, go to the menu
2. Click on Admin
3. Click on Users
4. Click on Add User
5. Enter user details, including a termination date that is in the past.
6. Save the user
7. Ensure that "Include terminated users" is not checked
8. Click the Download Members button
9. Notice the terminated user is included

Expected behavior
Terminated users are only included in the CSV file if the "Include terminated users" checkbox is checked.
