Hitting A-o stacks up "deselects" even though there is nothing more to select.

Summary

Hitting A-o stacks up "deselects" even though there is nothing more to select.

Reproduction Steps

1. Open a file.
2. Keep hitting A-o until whole file selected.
3. At this moment, as many times as you keep hitting A-o (everything is already selected, so nothing happens visually), the same amount of times you need to hit A-i to "undo" it before you start seeing things deselect (it basically buffers up, even though there is nothing else to select).

This should be a small fix: we just need to check if current_selection is the .last() of the view.object_selections vector, and if it is, don't .push the current_selection

	// save current selection so it can be restored using shrink_selection
	view.object_selections.push(current_selection.clone());
