templatekw: clarify the result of {latesttag} when no tag exists
My initial expectation was that the list would be empty, and therefore
detectable with {if()}. The map for {latesttag()} is populated with real values
in this case (except {tag}), so it probably doesn't make any sense to change
this to an empty list.
