Fails to start without flags

[jbeich]

Regressed by 2f4006dc3ddf. When config file doesn't exist yet swayimg constructs a synthetic one from command line flags but when no flags are specified the config remains uninitialized (NULL) which aborts (EXIT_FAILURE) runtime.

$ swayimg /path/to/foo.jpg; echo $?

$ swayimg -a test /path/to/foo.jpg; echo $?
