ajsf: Production build using AOT is not working.

Hi, at first, thank you very much for creating Angular6 version of this library. We using them on our projects and update to angular 6 is one of my current tasks.

We faced various type of errors which we can fix somehow (see our fork: https://github.com/jakubjosef/Angular6-json-schema-form). Right now we have working version (except custom layouting which is also not working and it’s very important for us) but in general we have working version but this version cannot be compiled for production use using AOT. We see very weird error:

 ~/xxx/xxx   angular6  yarn build:prod
yarn run v1.7.0
$ ng build --prod

Are you using this library in some application? Can you help us a little bit with debugging / fixing this issue?

Thank you very much in advance @hamzahamidi .
