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 #19959 to regress.

see #20971 for trunk.
