[WRTjs][VD] Send 'tizenvisibilitychange' event in app load-finish

In RWI scenario, an empty page will be loaded firstly,and
window is shown, at this time, WRT will send 'tizenvisibilitychange'
event to app, but app is not loaded, so app cannot receive it,
after RWI popup is closed, app will be loaded, but WRT will
not send 'tizenvisibilitychange' event anymore.
For this case, WRT will send 'tizenvisibilitychange' event in
'load-finish' event(app load), and just send once.
