Added speedprofile and speedfactor to vehicledata. This should be defined in the vehicle instead of the routing problem settings, but when sending vehicles without speedprofile and speedfactor NFleet-API sets them to the values specified in the routing problem settings.
If not specified the default values are Max100Kmh and 0.9.
Updated TestData to use the TestHelpers create-methods.
Fixed tests.
Made it so that tests create new user every time.
