Always select items on activation
There is an unintended side-effect in d3839617 which this MR fixes. Normally in Dolphin, when clicking on an item to open/activate it, it is both selected by the click and opened/activated. Prior to this MR, the item wasn't selected when all of these conditions were met: - Use ActivateItemOnSingleClick also knwon as single-click mode - Have more than one item selected already - Click on an item that was previously not selected Prior to this MR, the click would deselect all items and activate the clicked item but not select it. With this MR, the click will deselect all items, activate the clicked item and also select it and move the anchor there. When testing this with folders, make sure to navigate back after activating the folder. The folder should then still be selected. This is then consistent with the behaviour when the specific conditions mentioned above are not met.
