Improve expect(stub).secondCall.calledWith(...) error message when called once

[kuceb]

Current, if the stub was only called once, and you try to chain something off .secondCall, you get a terrible error message:

// stub was only called once
expect(stub).secondCall.calledWith(...)

TypeError: Cannot read property 'calledWith' of undefined

Desired Error message:

"Error: expected stub to be calledTwice, but it was only called once"

This also goes for firstCall, thirdCall, and getCall(n)
