Blueprint shows text of the first item of the personal_urls in its navbar-right using

{{! HACK: personal_urls.0.text not working }}
{{#each personal_urls}}
    {{#if @first}}
        {{text}}
    {{/if}}
{{/each}}
{{! /HACK }}

I think this used to the username, but on LSG site these days the first is pt-uls (the Universal Language Selector, text is "English"), not pt-userpage.

Note @first doesn't work with core's "mustache-only" version of PHP templating.

The fix is to add server-side logic to provide the necessary piece of data, same as for the sidebar.
