iOS18 issues restoring sessions

- Found this due to mosh sessions not saving and restoring properly sometimes.
- The UIPageViewController has changed internally when some events are called.
We cannot rely on ViewWillAppear before for certain cases like restoring the
state, so it is now done after the PVC is done with the transition.
