Fixing problem where organic isn't shown properly

Fixes #1361

[5ila5]

Did some digging myself and found:

• first two test cases seem to be no longer work and addresses are not listed on their website (change street number (810 -> 813, 599 -> 597)
• this approach of seems to only work on address where garbage and recycling collections are not at the same day (like 597 Darling Street ROZELLE) and ignores organic collections on addresses where garbage and recycling are on the same day (like 29 Lackey Street SUMMER HILL)

Maybe you can check if there is a better approach to this. I noticed that we get the collection dates differently than the web page. maybe we should use the API the website uses to populate the calendar.

edit:
I would also like to raise an exception instead of returning [] so that uses have at least something in their logs instead of just not getting any data

Thanks @5ila5 I'll look into those problems.

Didn't realise how much of a variance there is in our local area on the waste pickups...
