Makes chai-iterator compatible with chai 4; closes #12

[harrysarson]

This is a breaking change.

Applying either 18246bb or cc0cab6 by itself causes tests to fail.

Mergin this pr would require bumping npm to version 2.

@harrysarson Have you considered publishing your patched version of chai-iterator under a namespace on npm? It would help a lot of downstream users.

[harrysarson]

@TimothyGu I have done :)

hi, guys! @harrysarson thnk you for package https://www.npmjs.com/package/@harrysarson/chai-iterator
but does anybody know will be this package updated here(https://www.npmjs.com/package/chai-iterator)?

[harrysarson]

Hi @iamsimakov, I have reached out to @mcmath by email as described in https://docs.npmjs.com/misc/disputes about three weeks ago.

I haven't yet heard anything back so I am hoping that the folk at npm might be able to transfer ownership. Once that happens I will release version 2 of chai-iterator with these updates.

[harrysarson]

@iamsimakov I have released version 3.0.0 of chai-iterator.

[iamsimakov]

@harrysarson Thanks!

[harrysarson]

Does it work ok for you?

[iamsimakov]

@harrysarson I'm sorry but I can not check this version now, I will try it few days later, thanks
