The separate setup method was introduced in 2014 via I7c3c133.
It appears like most of the code here was written before this
method existed. Let's update it.
* this.outlineItem is guaranteed to be set. No need for the `if`.
* The parent method is effectively abstract. There is no point in
calling it, I would argue.
* The return value is never used. I.e. this method is never
chained, and probably shouldn't.

Generating the templatesUsed list is relative slow, and is only
used in an obscure part of the editor, so only generate it when
needed.
