Pending User link doesn't filter to pending users

[d2roth]

When receiving the email sent via approve_approval_email to the administrators, the admin_url just goes to the all users page and not to the pending users' filtered view.

I tracked the issue down to the URL that is being created. The URL generated is using the wrong url parameter. It uses new_user_approve_filter=pending instead of new_user_approve_filter-top=pending, notice the "-top".

Here is the line where the parameter is incorrect:

If you want I can create a pull request with this fix.
