Bug: RendererManager.removeControls() is misnamed actually removes a renderer

[GaneshPatil7517]

In renderer-manager.ts:164-170, the method removeControls(renderer) splices from this.renderers rather than removing controls. This is a copy-paste naming error that makes the API confusing and may cause callers to miss the actual renderer removal method.
