This addresses a bug where specifying an integer after key on an unmapped field for a terms composite source caused the shard to error. Resolves elastic#85928 The after-key parsing is pretty weird, and there are probably more bugs there. I did not take the opportunity to refactor the whole thing, but we should. This fixes the immediate problem by treating after keys as bytes refs when we don't have a field but think we want a keyword. We were already doing that if the user asked for a missing bucket, this just extends the behavior in the case that we don't. Long term, the terms Composite source (and probably other Composite sources) should have specializations for unmapped fields. That's the direction we want to take aggs in general.
