With this commit two calculation errors are fixed
* the score in the case partyPosition = 'negative' while userPosition = 'neutral' shouldn't be MIN_POINTS but rather BASE_POINTS.
* the totalScoredPoints (now "totalMaxPoints") should be independent of any party-positions which it wasn't.
To minimize errors in this area in the future tests are added
which are based on the official Rechenmodel of the bpb.
To that end the score calculation logic was refactored
and moved from results.vue to scoring.js, too.
