Fixed 801 Users can edit name in their profile pg

https://openhatch.org/bugs/issue801  Tested locally, it works. I made the UI as similar as possible to the "edit location" url link at the top left corner of the user's profile page. 

In addition, I made the design decision to remove the `<a href='/people/{{ person.user.username }}'>` in base_profile.html, because this url link redirects users to the same current profile page and also having that link plus the `href='{% url account.views.edit_name %}` link is confusing for users who want to only click on the "edit name" link.
