[Android] Speculative fix: use WaitUntilFullyBooted in telemetry.

[Android] Speculative fix: use WaitUntilFullyBooted in telemetry.

adb wait-for-device (and thus AdbWrapper.WaitForDevice) can return before
the device is completely ready for use (see e.g. crbug/493900). Switching
to DeviceUtils.WaitUntilFullyBooted ensures that the device is either
ready or is irrecoverably gone.
