GitSubmitEditor: Simplify update of files model

Browse Source 
Report the commit data fetch result, including success state and error
message, through the QFuture. That also removes the need for creating a
fetcher QObject and the logic to make sure it is deleted.
Also exchange QtConcurrent::run by Utils::runAsync.
