Make options optional

[doug-wade]

Currently, with the minimal config,

gulp.task('snyk-protect', function(cb) {
	return snyk({command: 'protect'}, cb);
});

gulp.task('snyk-test', function (cb) {
	return snyk({command: 'test'}, cb);
});

I get the following error:

doug-UX301LAA packages/generator-clefs-plugin ‹switch-to-snyk› » gulp prepublish                                                                                                                                                  1 ↵

However, when I add the options hash

gulp.task('snyk-protect', function(cb) {
	return snyk({command: 'protect', debug: true, options: {}}, cb);
});

gulp.task('snyk-test', function (cb) {
	return snyk({command: 'test', debug: true, options: {}}, cb);
});

it works as intended
