Users who have not yet been approved cannot be deleted

[fsando]

When a user applies for access they are created as user and a token is stored in a special table until they are approved.

As long as the token is in this table (i.e. as long as the user is not yet approved) they cannot be deleted from the user table, apparently because of foreign key constraint.

I believe this can be corrected by changing the foreign key constraint to ON DELETE CASCADE on the token table.

Actions to replicate:
Apply for access on the front page of dbnp by clicking the signup button and fill in the form.
After this, log in as admin and try to delete this user WITHOUT approving them.

Expected behavior:
The user should be deleted.

Actual behavior:
The user is not deleted.
