Account Tracker / Hill Lists / Meter Readings

Fixed a crash that a very small number of users encountered shortly after launching or unlocking the app.

Please let me know if you come across anything (else) not working.

NOTE: this will likely be the last release of Account Tracker that supports iOS 8. My next update will only support iOS 9 and above. Older version of my app (and iOS) will continue to work, but you will no longer get updates.
