Bundled Themes: Use `display` context for `get_bloginfo()` in `wp_title` filter

[michelwppi]

as developer of xili-language multilingual plugin, after a support enquiry, I discover that wp_filter (twentythirteen_wp_title function) inside functions.php of 2013 show a issue:

to display blogname you forgot to add second parameter 'display' in

get_bloginfo ('name');

as done in wp_title for description ( see #25808 )...

get_bloginfo ('name', 'display');

By using this parameter, get_bloginfo is filterable (apply_filters at end of function get_bloginfo ) as wp_title used in header...
I think it will be coherent to be done in parent 2013 and not with a remove filter in child theme and add a new fixed filter...

Happy new year

Makes sense. Let's do the same for all the default themes that use wp_title filter.

In 27091:

Default themes: Use the 'display' filter for get_bloginfo( 'name' ) attached to the wp_title filter.

props michelwppi.
fixes #26811.

lancewillett and I decided that we would be leaving all bundled theme tickets for 3.9. Given the timeline (and lack of severity) we won't be doing a theme update before then.
