Fix broken URL in error message (#6365)

The `/me` route has been changed into a redirect to `/settings/tokens` due to it being hardcoded in cargo for a specific purpose. The email address field has moved to `/settings/profile` though, so this commit fixes the error message to point to the correct page.
