* adapt for structure change in gql backend (e.g. id -> rowId)
* display questions not rowId dependent anymore
* fixed calculation error if both, party and user, selected "skipped"
* fixed problems occuring when a candidate hasn't answered all questions (yet)
Also
* reorder graphQl queries: Always a query constant + update function
* use id instead of token (initials) to identify person in url
* Remove any party logo related sections since currently not needed
* Move "options" from data closer to actual code since it doesn't really belong to data
(data may be deleted in the future, anyway)
* add nodeId in gql queries wherever possible to avoid problems with the apollo cache
* add note about graphql schema import to README.md
