Check protocol Class before creating a StatJob

StatJob::mostLocalUrl only works with ":local" protocols, adjust the code
accordingly.

Make the code async.

Remove activeContainerLocalPath() method as it isn't needed anymore.

Drive-by change: minimum required version of Qt should be 5.12 because
that's what KF >= 5.73 already requires.
