Graph Editor: fix keyframe not activating in certain cases 

When clicking on an already-selected keyframe, mark it as active if the
click caused the previously-active keyframe to become deselected.

When clicking on a key in the graph editor, it is selected and all other
keys are deselected. If that key was already selected before the click,
it would not become the active keyframe. This is now fixed.
