[gnome-builder] project-tree: use gb_tree_node_show_popover()

    project-tree: use gb_tree_node_show_popover()
    
    Use the new helper to ensure the treenode is selected and onscreen before
    we display the popover. Otherwise, we can get an invisible popover since
    the geometry is not within visible coordinate space.
