[android] Decouple SensorHelper from LocationHelper

Browse source 
Compass and location are two different things. Rename SensorsHelper to
CompassHelper and extract it from LocationHelper to the upper level to
simplify LocationHelper.

Please note that SensorHelper is still started by LocationHelper to
avoid any semantic changes.
