Source for url-to-pdf-api

[vanthome]

You refer to this project in the README.md:

https://github.com/alvarcarto/url-to-pdf-api

But in the travis CI file, you are cloning it from here?

https://github.com/onesdk/url-to-pdf-api.git

Why are you cloning this outdated fork?

Noticed the same problem. Looks like this is not actually a Docker image for alvarcarto/url-to-pdf-api despite it being listed as such in the original project's README.

@e2tox any explanation why this is as it is?
