Subject: [PATCH] I18N, Script Loader: Don't register empty locale data
 objects.

For `wp.i18n` the library [https://github.com/messageformat/Jed Jed] was initially used which was throwing an error if a domain was not registered but used in a translate function. Later, the library was replaced by [https://github.com/aduth/tannin Tannin] which no longer requires the domain to be registered and thus we can avoid printing an empty-ish translations script that doesn't add any translations.

Props jsnajdr.
Fixes #55250.
Built from https://develop.svn.wordpress.org/trunk@52937
