test: Migrate muild-map-data.spec.js

- needs to be run as a component test, as it needs the App context
  including the store. It is therefore not in the __tests__ folder but on
  the same level as the script.
- added empty, skipped test bodies for missing functions
- issue #323
  there are currently 2 similar and confusing functions:
  - buildMapViewData: 'Build and returns map data'
  - buildMapData: 'Build the mapViewData object'
- remove old spec
