Fixing wp_title in extras

It was checking if we’re on an older version than 4.1, and gets the
full title passed to the function, and appends.

Correct, that is what the code is supposed to do. If we're on 4.1 or later we'll use add_theme_support( 'title-tag' ); and don't care about the wp_title callback, because the built-in feature does that for us.

We also want to only append the blog name as to not overwrite the true title. We want to enhance it, not replace it.

Not a relevant PR anymore. See #798 and 8e9678b.
