Challenges & Sponsorings should be refactored. Proposed idea:
Everything is an abstract Challenge, where each implementation is a different variation of the challenges that are available in our system (e.g. OnetimeChallenge, RepeatingChallenge, DistanceChallenge)
Also, UnregisteredSponsors are more loosely coupled, as both UnregisteredSponsor and Sponsor implement the ISponsor Interface
