1. Open attached "ScriptsOnly" project
2. Press Build&Run, overwrite the "Build" apk that is already in folder

Expected result - Application is installed to device and launched
Actual result - Application is not installed to device. If older app version is installed, Unity launches older version of the application and reports a build as successful. If older app version is not existent on device, Unity just reports build as successful, but you can see that no app is installed or launched on device.

Notes:
1. As mentioned, if the device has older app version installed, Build&Run just simply launches older version of the app. This does not happen with Patch&Run, new application is successfully installed and launched
2. Happens both with Mono and IL2CPP
3. Reproduced both on macOS 10.13.6 and Windows 10
