Great start @MathijsVerbeeck, made a few comments while reviewing. Could you have a look at them, please?

Let's do some more changes. It seems like you missed some of my previous comments, or they were not clear enough. If the latter, sorry for that, you can always ask more context.
Another thing, currently we have a lot of files (pa, pp, flow, ...) where we stub the wrong function. Right now we do:

sinon.stub(accessToken, 'isAppOnlyAccessToken').returns(false);
    auth.connection.accessTokens[auth.defaultResource] = {
      expiresOn: 'abc',
      accessToken: 'abc'
    };

While in fact, we should just stub the assertDelegatedAccessToken function.

Sorry for the inconvenience... I had some merge issues on my laptop and decided, instead of fixing them, to work on a clean branch on my desktop, which is why I must've messed up some of the comments you had already given.
