This commit is a bugfix. When adding new nodes with the node menu, the selection was never explicitly cleared and nodes were added to the selection rather than being exclusively selected. This behaviour used to be hidden when the node menu could only appear with a right click, as the click would automatically empty the selection. However, with the node menu being now openable with the TAB key, there might not be a click to empty the selection. If new nodes are added by opening the menu with the TAB key and using the arrow keys to select the node to create, an infinite number of them can be created and added to the selection.
