sim:tests: shodan_boot.robot workarounds

- ProcessMaanger log msgs race against application-generated log msgs;
  workaround this by not waiting for the ProcessManager msg saying an
  application Bundle was started
- When running the mltest app install the model before the app; this is
  a hack to workaround a resource management problem
