What's in this PR?

Index or reindex shadow documents with original locale

Why?

Shadow pages are not being indexed

• Go to sulu.rocks
• Unpublish coyoos page in 'de'
• Set shadow page with 'en'
• Change something in English version
• https://sulu.rocks/de/search?q=coyoos ( 0 results )

I don't know if WorkflowStageBehavior must be taken in count in this case
