Jarek Kobus d95fa019d4 PythonSettings: Don't leak running watchers ...

Detected by memory analyzer.
When shutdown comes while pythonsFromRegistry() or
pythonsFromPath() is still running, the corresponding
QFutureWatcher is leaked.

Employ TaskTreeRunner instead. It handles the cancellation
of the running tasks automatically on its destruction.

Make pythonsFromRegistry() and pythonsFromPath() cancelable,
by providing QPromise as a parameter and check for canceled
state on every iteration.
