project controls stop working if a project gets stopped during build step

If a project is being built and the stop button is clicked from the miniproject widget or from other stopping buttons, then the build stops, at least the logs stop coming in, but that's it, Creator keeps showing that the build is going, and controls stop working, they're clickable but they do nothing, stop, debug, start any of them.

This is noticed on a debug build of Qt Creator 5.0.1 for macOS and Android kits at least.
