/**
* Initialization method that has 3 different behaviors based on whether bookmark model is loaded.
* If the bookmark model is not loaded yet, it pushes a loading state to backstack which contains
* the url from preference. If the model is loaded and the backstack is empty, it creates a state
* by fetching the last visited bookmark url stored in preference. If the bookmark model is loaded
* but backstack contains a pending loading state, it creates a new state by getting the url of
* the loading state and replace the previous loading state with the new normal state.
