IssueTracker

I was building a sample project with 7.3 dev, and as I was trying to run the app, the build failed with a lint error. I was not expecting this, because the current variant is a debug variant, and lintVital should only be running on release variants. See screenshot. The test project is https://github.com/android/architecture-samples though I have some local tweaks (but not to the variants setup).
