Fix custom options being overridden on execution

If one sets an option that will be later overriden by `-a` (for instance `--no-p` ), the current behaviour dismiss that option.
Since the options manually added to the configuration file are meant to be overrides, this change adds them a=fter the defaults instead of before.
