Use `prepare_original()` in editor for strings with plurals as well

[vladytimy]

In the translation-row-preview.php template, prepare_original() is used for strings both with a plural and without. ​See template.

In the translation-row-editor.php template, prepare_original() is used only for strings with no plural. ​See template.

So, the editor for strings with plural are missing this filter that:

• replaces new lines and tab characters with visual symbols. See ​this example here where only the preview has them, but not the editor.
• wraps non-translatable items with a notranslate class that can be used by various extensions or even GP in the future.

Unless there is a valid reason not to do so, I suggest we apply prepare_original() to plural originals in editor as well.

Note: Although this inconsistency is present in GlotPress itself as well, we use a custom template for translation-row-editor.php so the fix for translate.WordPress.org is here. A similar issue will be opened for GlotPress, but we need to fix this on our side.

@vladytimy was an issue opened upstream?

In 11316:

Translate: Apply prepare_original() to the originals display in the translation editor.

Props vladytimy.
Fixes #5923.

I also tested this with glossary entries, ​https://translate.wordpress.org/projects/wp-plugins/test-plugin-3/dev/en-au/default/?filters%5Boriginal_id%5D=9692098
