v8 backend: sometimes scriptLoaded event is not emitted

[GoogleCodeExporter]

Fix: 
https://github.com/develar/chromedevtools/commit/1936aab9607d6c6cecaaf00f0365251
d88466a49

Real reason: V8Helper.reloadScriptAsync SuccessCommandResponse handler doesn't 
call "debugSession.getSessionManager().getDebugEventListener().scriptLoaded" as 
AfterCompileProcessor.messageReceived SuccessCommandResponse handler does.

So, I moved this call to ScriptManager.addScript
