CocoaPods still used instead of SPM

[ikurek]

I raised this matter before in #329 - right now I added the plugin to another project and by default it still fetches CocoaPods (I do not have pods in this project at all, so it's not caused by any other libraries. Here is my doctor output:

I'm using open_file: 3.5.11, I also trued fetching directly from git with

  open_file:
    git:
      url: https://github.com/crazecoder/open_file.git
      ref: master

but no matter what I do the dependency always requires Cocoapods. @vicajilau issued a fix for this in #331 but I think there may be something else wrong with SPM configuration
