orderby param of include passed with no include value

[mogmarsh]

Description of the bug

On load, a block can send a request that looks like this: /wp-json/wp/v2/posts?context=edit&offset=0&orderby=include&per_page=1&type=announcement&include=&_locale=user
which returns

{
    "code": "rest_orderby_include_missing_include",
    "message": "You need to define an include parameter to order by include.",
    "data": {
        "status": 400
    }
}

Steps To Reproduce

Set up a Query block with a query that will return no posts.
The backfill request will be sent passing either null or commas (depending on the number of posts) as the include parameter.

after more research, it appears this happens when a term selected in the query is deleted. The term name is stored as well and will continue to show in the filter even if the term is gone.
