ng2-material-dropdown results in undefined injector type

[stevenkampen]

In this line of the ng2-material-dropdown component, the first injected dependency returns a type of undefined using reflect-metadata, which breaks Augury.

Some investigation is need to determine why this happens.

@souldreamer, this is your issue which you originally reported on #848.

Refactoring the project to use a service instead of the forwardRefs makes it work with Augury, so it's definitely something to do with those. Here's a version that does this: https://github.com/souldreamer/ng2-material-dropdown

@souldreamer Ok, I guess it's a forwardRef specific thing, which I can test easily enough. Thanks for the context.

I have the same problem with https://github.com/Gbuomprisco/ng2-material-select. However, the stack trace doesn't show anything related to the code of that component.
