Support .returns() with static value

[parisholley]

It is annoying to always use a function because of the following use case:

interface Wee {
  value?: string
}

let test:Wee = {value: 'foobar'};

if (test) {
  mock.setup(m => m.do()).returns(() => test);
}

typescript will complain because test can be "undefined"

Hi @parisholley

The author of Typemoq, @florinn, hasn't been active on Github for a couple of years now. In order to keep Typemoq progressing I have created a fork over at https://github.com/typemoq/typemoq-continued where I would like us as a community to continue development while Florinn is absent.

If you would like, I invite you to create a PR over on that repo where this feature can then be merged in. The new repo is on NPM under typemoq-continued.
