[Failing Test] Preserve resolvers of types that are waiting on asynchronous operations

[lemonsrc]

This PR is in reference to this issue:
#105

Mocked types are sent to that types resolvers before RootQuery async operations complete causing resolvers to not be preserved.

It is expected to receive the resolved type from the RootQuery in that types resolvers; however, according to this failing test, a mocked version of that type is received first when the RootQuery returns a Promise and other asynchronous operations like async / await.

@lemonsrc thanks for the PR. It would be great if someone could pick this up and submit a PR with a fix. I'd be happy to give pointers. Any volunteers?

@lemonsrc On closer inspection, I think this has nothing to do with the fact that the resolver returns a promise. Rather I think it's because it's a root type, whose fields get handled separately from non-root types. I think it should be a pretty quick fix, if you want to give it a try!

@lemonsrc I think I may have introduced that bug a few days before you reported it. I fixed a few things since then, and added some tests, see recent commits in #115, let me know if that works for you.

So it turns out I was wrong and this could indeed have been related to promises. Let's make sure we fix both of those potential issues! @lemonsrc if you don't mind, we'll close this PR and pick things up in #115?

@lemonsrc can you confirm that this works now on master, and if it does close this PR? Thanks!
