[Navigation Tree] Whole tree item clickable (#3638)

* passing click and context click on tree item down to object label, making the whole tree item interactive

* removed unnecessary code

* WIP: removing propagation prop from view control and just stopping all propagation

* capturing click on tree item and then calling the click handler on objectLabel, this prevents multiple events and handles all clicks in the tree-item

* removing unnecessary ref

* ignoring clicks for view control so it can handle them itself

* made view control class a constant

* replaced class-based checks with ref-based checks

* removing old leftover code
