Didn't find any valid dependency graphs. - Flask and websocket-client

[feelfreelinux]

In my app I use both flask and websocket-client. However, when i try to add both of these dependencies to my app, p4a fails. However, when I build my app only with flask, or only with websocket-client p4a works correctly.

p4a apk --private /home/user/sample/ --package=samplepackage --name="Sample app" --version 0.1 --bootstrap=sdl2 --requirements=python2,websocket-client,flask
[ERROR]:   Didn't find any valid dependency graphs.
[ERROR]:   This means that some of your requirements pull in conflicting dependencies.

Assuming websocket-client doesn't really depend on Kivy, the issue is that Kivy is listed in its requirements.

Well this is actually nastier than it looks trevorjamesmartin/websocket-client@29b91ee
So basically it looks like the recipe links to a fork that hacked in kivy logging.
The funny thing is it was forked without making it obvious, but I'm assuming the original repository is that one https://github.com/websocket-client/websocket-client
I'll make a PR to fix all of that.
Edit:
Here's the (untested) pull request #1513
@feelfreelinux can you give it a try?
