I think I slightly prefer having the one OnInjectionComplete method here.  If
the injection was blocked (and we have no run info), we can pass in nullptr (and
add a check in UserScriptInjector).

If we want to get run info for sync and async (without elapsed time) injection,
we need to divide this method because I need to receive information about run
somewhere in ScriptInjection::TryToInject for both type of injections.
