it on deactivation so we can restore it on requery().

Fix deadlock of WebViewCoreThread

There was a deadlock in destroy process.
Investigation showed that WebViewCoreThread is waiting some
callbacks but in this case WebViewCoreThread can not resume
itself not to call notify method.

Flow:
1. CallbackProxy.sendMessageToUiThreadSync
2. WebViewClassic.destroy()
3. CallbackProxy.blockMessages()
4. CallbackProxy.handleMessage is called via MainThread
5. The WebViewCoreThread deadlock is occured.

The cases we have to call notify method are followings.
OVERRIDE_URL
CREATE_WINDOW
SAVE_PASSWORD
NOTIFY
OPEN_FILE_CHOOSER
JS_ALERT
JS_CONFIRM
JS_PROMPT
JS_UNLOAD
JS_TIMEOUT
