Fix localised WordCamp logs

[dd32]

The current WordCamp status code filters locale which is the incorrect way to switch locales, causing logs to contain localised post_status labels, causing the logs to contain a localised status which is unmatchable and causes PHP Notices and broken UIs.

Fixes #1300 probably

There's numerous other uses of set_locale_to_en_us in the codebase, which likely do not work. The locale can't be changed at runtime simply by changing the value of the filter, the filter only changes which locale is initially loaded.

Suggested change

	add_action( 'init', array( $this, 'register_post_types' ) );
	add_action( 'init', array( $this, 'register_post_statuses' ) );
	add_action( 'change_locale', array( $this, 'register_post_statuses' ) ); // Re-register them when the locale changes, to have localised statuses.
	add_action( 'init', array( $this, 'register_post_types' ) );
	add_action( 'init', array( $this, 'register_post_statuses' ) );
	// Re-register them when the locale changes, to have localised statuses.
	add_action( 'change_locale', array( $this, 'register_post_types' ) );
	add_action( 'change_locale', array( $this, 'register_post_statuses' ) );

The post types can probably be reloaded too, to ensure they're properly translated, but I don't think they're used anywhere in logs so are likely less problematic.
