This allows the mobile UI to reflect the three states that the dive list can be
in:
- changes that haven't been written to local storage
- there potentially are changes in local storage that were not synced with the cloud
- dive list is in sync with cloud storage
The last state could be misleading if the user access the cloud from a
different device and makes changes to the cloud storage from there, but from
the point of view of this device, the states are consistent.
