    file-view: Always unset pending_selection after freeing it
    
    When a file view was loaded with a pending selection, and not all the files were
    seen yet, the private pending_selection list was properly free'd, but the pointer
    was not cleared, causing a crash when `nautilus_files_view_set_selection` was
    called again, as it was trying to deeply copy a list pointed by this invalid
    reference.
    
    So, removing the unneeded `pending_selection` temporary pointer from the main
    function scope, as it only confuses, while use it (with an autolist) when we
    need to pass the previous `priv->pending_selection` (stealing its ownership)
    to set_selection again.
    
    Eventually use a g_clear_pointer to free the list and nullify its priv reference
    
    Fixes #295
    
    
    (cherry picked from commit ae3382a281b018337a8032ef13663ec2d9c7fd6c)
