Good catch Firebase Test Lab Robo Test 😂

Thanks @danesfeder for patching it

NIT - Why did we change the order?

final CameraUpdate overviewUpdate = buildOverviewCameraUpdate(padding, routePoints);
CameraUpdate resetUpdate = buildResetCameraUpdate();

vs

CameraUpdate resetUpdate = buildResetCameraUpdate();
final CameraUpdate overviewUpdate = buildOverviewCameraUpdate(padding, routePoints);

Declare variables as close to their usage as possible.
