[gnome-packagekit/gnome-2-28] Do not attempt to refresh the updates list when a transaction is running

    Do not attempt to refresh the updates list when a transaction is running
    
    If a package adds or removes a .repo file during a transaction, the
    ::RepoListChanged() signal gets sent from PackageKit. If a tranaction is already
    running, then just ignore the signal and continue the transaction like normal.
