Description of problem:

When a token is created for a user, it all allows to invalidate all the users token by clicking "Invalidate Token" in the dropdown of Administer -> Users.

But when we `invalidate token`, the button remains enabled even after invalidating it.

How reproducible:

Always

Is this issue a regression from an earlier version:

No

Steps to Reproduce:

1. Create a user with permission to "edit_users" and "view_users".

2. Navigate to Administer -> Users

3. Invalidate other users token from that user.

Actual behavior:
[The invalidate button is enabled for the user even after invalidating all token for that user.]

Expected behavior:
[Button to "Invalidate token" should be enabled if there is any token to invalidate]
