Try harder to open GitHub links

Links that can't be opened by the app will try to get as close as
possible.

For example, if the app can't open
https://github.com/github/android/issues it will try to open
https://github.com/github/android/ and then https://github.com/github/
Don't search for open and closed as the legacy request doesn't work.

This is just a temporal solution, I've added a TODO to fix the request
ASAP
