investigate lowered coverage of /src/mocks/response/ in coveralls.io

Timeboxed 1h

PR #291 has lead to lowered coverage in all files in /src/mocks/response/ on lines which call super(new ResponseOptions(...)).

Local coverage report does not see these lines as as missed, but also does not see them as hit.

The reason for the lowered coverage is that typescript changed the way they call super constructors
See microsoft/TypeScript#13029

There are a few people telling that changing jasmine compilerOptions to es6 should solve this issue but i don't think this is the way to go.

I think the best is to wait until newer version will handle this issue. Or with adding a skip next line hint for jasmine on the typescript side or the remapper knows what to do.

Well researched @sandrozbinden, thanks! I agree, let's live with it until a fix emerges...
