(Ruby) Allow 'android-app' URL scheme

[turino]

Referer urls like
"android-app://com.google.android.googlequicksearchbox" are valid and
shouldn't cause an error.

This is related to #172, and almost identical to #145 . I've signed the CLA, so I'm hoping we can get this merged. Let me know if you need me to do anything else.

I signed it!

I had already signed when I submitted the PR. Does the CLA bot check before commenting/does that mean there's something wrong with how I signed?

[snowplowcla]

Confirmed! @turino has signed the Individual Contributor License Agreement. Thanks so much

[alexanderdean]

Sorry @turino, the CLA-bot is quite temperamental...

[dsingleton]

This looks like it's ready to go? 🎉

I was following #145, and we're still having the same problem, it'd be great to get this fixed :)

[turino]

@alexanderdean anything else I can do to help get this merged?

Added @BenFradet to review...

Thanks 👍 , sorry I missed it I was on hols when you opened the pr.

Could you rebase against develop, then I'll merge?

[turino]

@BenFradet done!

[BenFradet]

Merged, thanks @turino 👍

[turino]

Thanks! When will we see a new version of the gem?

We actually want to split this repo up by language in https://github.com/snowplow-referer-parser (I actually just created https://github.com/snowplow-referer-parser/ruby-referer-parser) to be more agile regarding releases.

I guess we won't be making releases until the above is done. Any help easing this process would be greatly appreciated 👍 .
