<h3>Log Message</h3>
<pre>If a plugin triggers the WP_Scripts constructor prior to init, fire wp_default_scripts()
then and again on init.

Only add our localized strings once we've fired init, in case we do have the situation
where we fire wp_default_scripts() twice.

Fixes issues where plugins or themes try to enqueue a default script handle prior to
init. Does not allow <a href="http://core.trac.wordpress.org/ticket/19959">#19959</a> to regress.

fixes <a href="http://core.trac.wordpress.org/ticket/20971">#20971</a> for 3.4.</pre>
