r=me with some fixes

NIT: you don't need to save this to a variable if it's only used once

> Source/WebInspectorUI/UserInterface/Debug/Bootstrap.js:155
> +            mockWebExtension = null;

this doesn't appear to be created anywhere

Do you wanna `WI.reportInternalError` so that the Uncaught Exception Reporter is shown?

> Source/WebInspectorUI/UserInterface/Debug/Bootstrap.js:167
> +            console.error("Problem creating mock web extension tab: " + result);

ditto (:161)

> Source/WebInspectorUI/UserInterface/Debug/Bootstrap.js:171
> +    WI.settings.engineeringShowMockWebExtensionTab.addEventListener(WI.Setting.Event.Changed, updateMockWebExtensionTab, null);

I think the `null` will cause an assertion to fail, as we need to have a `thisObject` in order for `WeakRef` to work properly.  You can use `WI.settings.engineeringShowMockWebExtensionTab` as the `thisObject` since it's the first thing checked inside the listener (and it matches other things).

Oops.

Good idea.

Oh, I totally forgot about that change, but it's coming back to me now. Thanks for explaining.
