Add Sinon.assert.calledOnceWithExactly

[dpmott]

Is your feature request related to a problem? Please describe.
Closely related to #1247, but in this case I'd like to be able to type Sinon.assert.calledOnceWithExactly(stub, arg1, ... argN)

Describe the solution you'd like
I believe that there just needs to be an entry in assert.js to facilitate this. I'm not entirely sure what the failure message (including interpolated variables) should be though.

Possibly just this addition to assert.js?
mirrorPropAsAssertion("calledOnceWithExactly", "expected %n to be called once with exact arguments %D");

Describe alternatives you've considered
The equivalent functionality with today's Sinon is:

Sinon.assert.calledOnce(stub);
Sinon.assert.calledWithExactly(stub, arg1, ...argN);

If I could get some agreement on what the assertion message should be, then I'd be happy to generate a PR.

@dpmott This is possible with a spy assuming you're on the latest version. The beginning of the page says, spies can record arguments which is what you seem to be looking for. Stubs are only for pre-programming behavior like forcing a function to return a specific value. Hope this helps!

@brandonau24 I believe you are talking about something else. @dpmott is addressing the feature disparity between the assertions available on the spies and the standalone assertions that can be invoked on spies. Furthermore, everything a spy can do, a stub can do as well: a stub simply extends the spy api. So all the spy assertions are already available on a stub, so you can always use a stub in place of a spy - it's more of a semantical discussion whether or not to explicitly use a spy.

@dpmott I'd try to make the assertion message even clearer (ref 88a7150 and the whole discussion in #1971 (comment)).

+ What about "expected %n to be called once and with the exact arguments %D"?
- What about "expected %n to be called once with exact arguments %D"?

So, yes, please provide a PR :-)
