[Bug] Can't render ScaleOverlayTool

[lwamuhaji]

Describe the Bug

The ScaleOverlayTool annotation object is successfully added to the annotation manager at its first call of _init() function in which addAnnotation() is called, however, as of second call of it, addAnnotation() is not called. That's because viewportsWithAnnotations that stores which viewports have an annotation prevents _init() from calling addAnnotation(), but there is no logic removes viewports from viewportsWithAnnotations array. So even after removing annotation with something like annotation.state.removeAllAnnotations(), you cannot add ScaleOverlay annotation again, which results in fail of rendering scale overlay.

Steps to Reproduce

1. Enable ScaleOverlayTool (this will call _init())
2. removeAllAnnotations()
3. Enable ScaleOverlayTool again
4. Uncaught TypeError from ScaleOverlayTool.renderAnnotation()
