    project-tree: Unselect project file after expansion
    
    In gb_project_tree_actions_refresh, we call gb_project_tree_reveal on
    the project file to expand the tree, but the project file ends up
    selected as well. This commit fixes that by adding an ide_tree_unselect_all
    function and makes use of it. (In most cases when you do a reveal it makes
    sense to have the node selected, just not this one).
