Fix wrong pause/resume state of wathcface

Fix wrong pause/resume state of wathcface

Considering 3 entry point for manual render start

1. Pre-Visilibity Event (Only for LCD ON State)
2. AppControl Event
3. Evas Object Move Event

For LCD Off/Evas Object Move Event case, wathcface will be paused by auto visibility check
But in case of AppControl, there is no visibility check to pause watchface.
So add new timer for 200ms to check iconify state.
Once watchface got resume on iconify state, the timer will check it's visibility and pause the watchface
