Delete page from edit.php does not remove page from elastic database

Based on issue https://github.com/10up/ElasticPress/issues/1827, I’ve created a PR, which should prevent this from happening.

Unfortunately, on Github, it’s very quiet, that’s why I also post it here.

My solution: https://github.com/10up/ElasticPress/pull/1831

Could anybody have a look at this, and if it makes sense, merge it, as how it is now, does not work as required.

Kind regards,

Edwin
