Fixes some issues with the location button being invisible (#207)

* Fakemobileclient should return a dict of wifi.data, instead of data, since we have bluetooth beacons too

* Use dict instead of list for beacon measurement in fakemobileclient and editor script

* Use distance directly

* BeaconMeasurementDataSchema add default

* Route from current location

* Do not try to set Score if no location found
