Title: Improve cfx experience on mobile:

1/ Print only the error message, instead of the full stack trace.
2/ Prints detected mobile app name on the device, when we pass an inexisting one.
3/ Prints available option for -a/-app when we give a wrong value.
4/ Print error message in order to add --force-mobile when we pass -a/--app fennec/fennec-on-device.
