Wallpaper: Allow multiple partners to be loaded

Current implementation only allowed for one partner, and any
additional partner wallpapers would not be loaded.
Partrner.get() still returns the first partner and a new method,
getAllPartners is introduced which returns a list of all partners.

Ticket: FEIJ-410
