Season winner is not registered on month end

Right now there's a bug in the CF that prevents this from happening. Please fix, as adding winners manually to the DB is very tedious and error prone.

Did a test run, seasonal winner function works just fine with current season (5 players only). Might be some corrupted user data. Have to test a bit more later on this season.

hmm... strange.. maybe the cloud function just didn't run as expected on month end then?

or, as you said, there might be some 'legacy'/corrupted users involved that don't have all the correct fields.

Added more logs for seasonal winner calculation for now so we can take a better look by end of this month.

Might as well create a PR for this so that what's currently deployed to Firebase is identical the main branch.
