pep8ify won't run multiple times

[sauln]

First off, thank you for this great tool! I've been using pep8speaks and it's automatic pull requests in all my projects.

Most recently, I've been working on a PR for a while and have tried using the pep8ify command multiple times, but it hasn't worked.

Steps

Initially, I issued the PR and added a comment @pep8speaks pep8ify. I then merged the suggested changes. A few days later, after more commits were added, pep8speaks updated correctly. Then I tried issuing the command @pep8speaks pep8ify again so pep8speaks would create another PR.

Result

It looks like, pep8speaks made a fork of the library, but never issued a pull request. You can see here pep8speaks/pep8speaks@5cfadbc that it even made the commits with the changes.

The PR I've been working on is scikit-tda/kepler-mapper#77. I have manually created a new pull request from pep8speak's fork.

Hello @sauln! Thank you for trying out PEP8Speaks!
I can confirm that this is clearly an issue since pep8ify is currently designed to be used only once per PR. Looking at the case of kepler-mapper, I think it should be redesigned to be called multiple times. Unfortunately, I don't seem to find much time to work on this in near future.

Hi @OrkoHunter. Thanks for getting back to me. I love PEP8Speaks!

As a temporary work around, I've found that if I delete my original comment calling pep8ify and delete pep8speaks' comment "Here you go...", then it will issue a second pull request.
