Manifest icon asset src

[zirho]

Shouldn't the icon src be hashed in manifest.xjson?

https://github.com/sysgears/apollo-universal-starter-kit/blob/master/modules/favicon/common/assets/manifest.xjson#L5

It seems broken to me in the example heroku site
https://apollo-universal-starter-kit.herokuapp.com/

This is what is expected.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://apollo-universal-starter-kit.herokuapp.com/

2. navigate to Manifest tab in chrome debugging tool
   https://developers.google.com/web/fundamentals/web-app-manifest/

3. see empty icon section.

@zirho I think to fix this issue we should use val-loader:

@larixer, How do you suggest doing it with val-loader?

Can we fix it by not hashing it for now, like it is done with favicon.ico?
