View subclasses were instrumented as render.render.* (Fixes 2552)

After digging through the commit history, I believe this is just a oversight when previous changes were made to the instrumentation system (f310d7, 9d13b7, 299cdf and friends), so I fixed it. Before this change, container view (for example) was instrumented under the name "render.render.container", now it's just "render.container".
