Typo and Iterator namespace reference

[helmut]

Cleaning up a minor typo and inconsistent reference to iterator.

Looks like the travis build failed due to some git api limits. Don't think it was anything I did?

I'll restart them now.

Hmm can't seem to restart the tests, @taylorotwell does it let you?

[bencorlett]

@daylerees @taylorotwell Just go to settings > hooks > packagist and hit the "test" button. This will force it to re-go.

@daylerees @taylorotwell actually that won't re-do the pull request. This pull request cannot possibly break code, it's safe to merge.

[daylerees]

@bencorlett oh I know. I was simply curious to find out if it could be done. Would be very handy for future requests. :)

Thanks for the pull @helmut !
