Update fastlane tool collector to work with mono repo change

[KrauseFx]

This fixes an issue where the version number of a sub tool wasn't properly recorded when calling fastlane scan ... after the mono-gem change

I was looking into how to add tests to this, however couldn't find a way to do so. We already have tests in https://github.com/fastlane/fastlane/blob/master/fastlane/spec/action_collector_spec.rb#L34-L37, and they're passing as they should, however they passed before.

The reason why the previous implementation wasn't correct is that when you call a tool with fastlane scan ... we might have never called require 'fastlane' and therefore don't have the actions loaded to check if it's a built-in action. It's safe to use the fastlane version as we're a mono-gem now, with the exception of plugins, where we want to load the actual plugin version.

I'd be ok with merging it as is, but if anybody has a better idea of how to add tests, I'm more than happy to update the PR. Basically this would require us to somehow unload the fastlane library I think

I think those existing specs cover this functionality well 👍
