Closing, mostly problem with a confusing repro output. Let's keep for the future.

@shcheklein It would be really great if you could specify what part is unexpected.

Issues that I see:

1. Double warning messages (modified output and then modified stage). The second message is not needed (it is already included in the 1st one).
2. It should not be a warning - regular DVC behavior. Just an output (not INFO either).

Anything else?

@dmpetrov it looks like I forgot I wrote that I'm closing this but forgot to actually close this. As far as I remember it looked to me that it was running something that it's not supposed to run - but turned out I was wrong. So, my intention was to close this and eventually create UI tickets when we get to repro.
