Don't fail jackd command line creation for jack dummy backend.

Browse Source 
The dummy jackd backend doesn't require a device to be specified, so much
of the error checking in get_jack_command_line_string() is irrelevant, if
not actively wrong, when the dummy backend is specified.

Only perform the checks if the chosen jack backend is not the dummy.
