Fixes undefined array causing warnings to log.
Modifies method signature of Mapper\Talk.

- Adds $admin_user_id as first argument of getAdminFavorites.
- This is done because createdFormattedOutput method requires the $admin_user_id.

A possible refactor would split the formatting method in two depending
on use-case. However, this depends on intent and I'm not entirely comfortable
with the codebase enough to know what the right decision is.
Added in missing info so Spot would stop complaining
Extracted code from PR129 as I didn't want the Spot related changes
