Turns out `fileName` is optional and maybe even `contentType`. We should revisit
this at a later point in time.

Scott Nonnenberg 6d8f4b7b6e 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!

Daniel Gasienica 2642844c27 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.

Daniel Gasienica 5d927b73e6 Use while loop for IDB cursor iteration 
Previously, I messily combined promises and callbacks because I thought we
were affected by the microtask issue:
https://github.com/gasi/idb#iteratecursor--iteratekeycursor

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