Bound the number of copies of a single local storage key

Fixes e-mission/e-mission-docs#1020 on android using #47

✨ New methods to return all keys and all local storage keys

The list of all keys is just for debugging. It allows us to answer the question: "when these local storage entries are deleted, is everything deleted? Or is there something special/unique about local storage?"

It would be pretty terrible if we are losing actual background information as well, since we would be losing trip data as well.

The list of local storage keys will actually be used in the phone code for working around the issue that the SQLite entries of the local storage type are sometimes deleted.
e-mission/e-mission-docs#930

We already had an issue in which the webview based local storage was getting arbitrarily deleted.

Since either of the entries can be deleted, we treat don't treat one as primary and the other as secondary. Instead, we treat them as co-equal, duplicate entries (similar to RAID :). We will use the keys to determine which ones are missing from each of the copies and copy them over properly.
