    Fix crash during the QFileSystemWatcher destruction
    
    The QFileSystemWatcher doesn't work correctly in a singleton
    The solution so far was to destroy the QFileSystemWatcher when the
    application quits but we have some crash with this solution.
    For the moment to workaround the problem, we detach the
    QFileSystemWatcher from the parent effectively leaking it on purpose.

    Fix solid test
    
    I need to detach parent on QFileSystemWatcher when the FstabWatcher
    destructor are called if the aboutToQuit is not called. It's the case in
    test.
