View state on Session and Team screens is preserved even if the Coach logs out/kills the app

Presently, if the coach kills the app without a save, they will lose the view state on various screens

The App UX should strive to make the most commonly used features accessible in not more than three actions. Saving their most common views will support this.
For example:
- Setting a Region Filter on the Session or Team screen will default to that same filter when the app is accessed the next time
- Setting a date range in the Session List will retain that same view the next time the screen is viewed

Some actions will naturally delete session cache, such as killing the app without a save. This is acceptable UX, for the time being.
