Fix PepperFlashSettingsManager::Core initialization.

Fix PepperFlashSettingsManager::Core initialization.

Previously, it is possible that before the newly created Core object is added ref by PepperFlashSettingsManager, Initialize() on the IO thread has caused the ref count to drop to 0 and destroy the object.
This change makes sure that PepperFlashSettingsManager holds 1 ref before doing the initialization.
