Nav: Move applyStateFixes from initializePreferredState to fixPresentation

We no longer have pinned nav available (currentState = 1 after page load)
so we don't need to set this padding in initializePreferredState. Having
it in fixPresentation makes more sense and it will be called on window
load to be sure fonts are loaded and it calcs the correct height.

Refactor initializePreferredState into the init function
