A results object for resolving an actor in a command with an unknown word or invalid phrasing in the predicate. For this type of resolution, we're trying to interpret the actor portion of the command as a noun phrase referring to an actor, but it could also just be another command. E.g., we could have "bob, asdf" or "east, asdf". Since we're only tentatively interpreting the phrase as a noun phrase, to see if that interpretation goes anywhere, we don't want to throw any errors on failures; instead we simply allow empty match lists.
