EditorFragment is missing the profiling stop calls

Only these calls are found in `onCreate()`:
```
        ProfilingUtils.start("Visual Editor Startup");
        ProfilingUtils.split("EditorFragment.onCreate");
````

Should also have these in onDestroy:

```
                ProfilingUtils.dump();
                ProfilingUtils.stop();
```
