[Typescript-angular2] Date in path is not correctly formatted for typescript-angular2 client

Description

The generated client does not format any date-time that is part of an operation path.

For an endpoint with this path:

/api/value/{date}/{id}

An example request (as generated by the client) would look like this:

http://localhost:5000/api/value/Thu%20Feb%2016%202017%2020:57:11%20GMT+0000%20(GMT%20Standard%20Time)/1

Command line used for generation

generate -l typescript-angular2 -o src/services/api/ -i http://localhost:5000/swagger/v1/swagger.json

Steps to reproduce

Generate the client then call the method "apiValueByDateByMetricIdPutWithHttpInfo" within TrackApi.

Suggest a Fix

The problem is being caused by how a date-time is formatted within the generated code. So for the example above, the client looks like this:

public apiValueByDateByMetricIdPutWithHttpInfo(metricId: number, date: Date, value?: number, extraHttpRequestParams?: any): Observable<Response> {
        const path = this.basePath + `/api/value/${date}/${metricId}`;

The problems is that ${date} returns the human readable string. What we want is the machine readable string format which can be obtained with ${date.toISOString()}.
