Wrong key resolving for ngModel in decorator.js

[senyaak]

In https://github.com/json-schema-form/angular-schema-form/blob/development/src/services/decorators.js#L193-L201 the ngModel won't get correct path if the directive will be called in ngRepeat, cause some key(s) well be an empty string.
Example we have ['lvl1','array','', 'value']
After resolving we'll get 'model['lvl1']['array']['']['value']' and this isn't right.
At this point if the key array contains an empty string, we should use a scope.$index for this key!

fyi, i believe the decorators.js link is out of date. I think this represents what @senyaak was linking to at the time this issue was created:

angular-schema-form/src/services/decorators.js

Lines 193 to 201 in 0a87024

	templatePromise.then(function(template) {
	if (form.key) {
	var key = form.key ?
	sfPathProvider.stringify(form.key).replace(/"/g, '"') : '';
	template = template.replace(
	/\$\$value\$\$/g,
	'model' + (key[0] !== '[' ? '.' : '') + key
	);
	}

@Anthropic i noticed you added the has: PR label, but i don't actually see one. Am i just overlooking it?

@zfarrell I have made changes in the webpack-babel branch to ensure the key is available which I believe will fix this issue. If you or @senyaak have any time, a unit test for this would really help me confirm it as fixed.

I believe this is fixed in the latest updates (alphas) for the eventual 1.0.0 release.

Please re-open if there are still issues in these versions and please make a plunker or gist to help me.
