Creating uncertainty annotations creates ingredient tags.

[Janchorizo]

If the asserted value for locus=name or the tag name is either ingredient, utensil,
or productionMethod, the a tag with such name is created. This is not the desired
behavior if we were to use lists of objects and the correspondent objectName tag in
the body.

[bug-rancher]

Fixed. I added validation for tag names and for now we can add only tags and certainties to tags from white list (date, event, location, geolocation, occupation, object, org, person, place, placeName, country, time). Adding elements to the lists works as before.
