[Angular2-typescript] generating var : "models.Collection..." instead of var : "any"

Hello,

The new version of codegen define collection in my object like

• someVar : models.CollectionSomeObject
  The old one
• someVar : any

The "CollectionSomeObject" are empty interface in both codegen versions.

The issue is :
-When i use an iterator on new version of "someVar" the compilator say that this is not an array or collection, which is actually true cause CollectionSomeObject is an empty interface.

I think that someVar : models.CollectionSomeObject is a good evolve but not if all the interfaces are still empty object.

The yml is generated from springboot with le latest release

a sample :
Now :
`
import * as models from './models';

export interface EtrTypechamp {
attribut?: string;

concept?: string;

etrSemantiquesByEtrTypechampid?: **models.CollectionEtrSemantique;**

etrSymptomesByEtrTypechampid?: **models.CollectionEtrSymptome;**

etrTypechampid?: number;

format?: string;

typeentite?: string;

}
**Before :**
import * as models from './models';

export interface EtrTypechamp {
attribut?: string;

concept?: string;

etrSemantiquesByEtrTypechampid?: **any;**

etrSymptomesByEtrTypechampid?: **any;**

etrTypechampid?: number;

format?: string;

typeentite?: string;

}
`
the collections in both versions are empty :

`
import * as models from './models';

export interface CollectionEtrSemantique {
}
`

The .yml.

swagger.zip

Start with the supplied .yml in swagger.zip and the Angular2 TypeScript generator output, comparing the generated model files for CollectionEtrSemantique and CollectionEtrSymptome with the Java Collection fields. Trace how these collection properties are represented and verify that the generated types support iteration without empty interfaces; done means the generated models have usable collection types and match the intended behavior.
