Backup: zipped messages.json, flat attachments dir
...
Backup creates, in a target directory:
- An attachments folder, with all attachments, each named for their
parent message's id - a GUID. If there is more than one attachment
in a given message, each attachment beyond the first will end with
'-N', zero-indexed.
- A file named messages.zip. It contains exactly what went to disk in
the original export code, but zipped up.
Export is now only 'light,' and in this new messages.zip format.
Import supports both the new format and the old format. If the target
directory has a messages.zip file, we'll treat it as the new format.
Next up: Encrypting attachments and the messages.zip!

Rewrite migration 17 without `idb`
...
We ran into issues when doing async operations inside of an IndexedDB
`onupgradeneeded` handler. The errors were ‘The transaction is not active’ or
‘Transaction has finished’. The following documentation confirmed that
transactions are committed/terminated when control returns to the event loop:
Spec
- https://www.w3.org/TR/IndexedDB/#transaction-lifetime-concept
- https://www.w3.org/TR/IndexedDB/#upgrade-transaction-construct
Stack Overflow
- https://stackoverflow.com/a/11059085
- https://stackoverflow.com/a/27338944
Since the initial database migration is so critical, I decided to avoid `idb`
with promise support for IndexedDB for now, but will reconsider using it for
other tasks in the future to improve readability of IndexedDB code.

ESLint’s `more/no-then` encouraged me to revisit this and it works as expected.
