[mobility_features]

### Describe the bug
onMobilityContext in this method not getting any callback even location update is working

### Expected behavior
/// Handle incoming contexts
void onMobilityContext(MobilityContext context) {
/// Do something with the context
print('Context received: ${context.toJson()}');
}
should get callback in this function and not printing any logs even i enable debug mode
MobilityFeatures().debug = true; using this way
