Autopkgtest: Drop trigger argument from fetch_swift_results()

Browse Source 
This could have led to (re-)fetching results more than once when we only got
the latest ID from the few triggers we were currently looking at, not for all
possible triggers of a package. Drop this kludge, and replace it with a proper
full iteration and caching.
