    * Fix of sequence number in IMAP IDLE expunge during deleting messages.
    * Fix not-returning empty result for UID dynamic range as said in RFC.
    * Separated IMAP to store and IMAP.
    * Store is responsible for everything about db and calls to pmapi, including event loop, sync, address mode.
    * IMAP is responsible only for IMAP interfaces.
    * Event loop is only one per ProtonMail account (instead of one per alias).
    * It also means only one database per account (instead of one per address).
    * Changing address mode is not destroying database, only buckets with IDs mapping (keeping metadata for account).
    * Before first sync we set event ID so we will not miss changes happening during sync.
    * Thanks to previous point we are not starting new sync when we finish first one because of unprocessed events.
    * Sync is not blocking event loop (user can get new messages even during sync).
    * Sync is not blocking reading operations (user can list mailboxes even before first sync is done).
    * Sync is not blocking writing operations such as mark messages read/unread and so on.
    * Most operations have to be passed to API and only event loop is writing them to the database.
    * Avoid relying on counts API endpoint; use event counts as much as possible.
    * Separate function for storing message content type and header into database.
    * Sequence number optimised for last item in mailbox.
    * Allow sending IMAP idle update to timeout to avoid blocking bridge.
    * Synchronisation will create a label if not yet present.
    * Labels and Folders (including system folders) are stored in DB together with their counts for offline read-out.
    * AddressIDs for all user addresses are stored in DB.
    * IMAP updates channel is set when an IMAP client connects (and IMAP updates are dropped until then).
    * DB keeps track of address mode (split/combined).
* Event loop starts as soon as user is initialised (i.e. logged in), not just when imap is connected.
* Use pmapi v1.0.13.
* Logout user if initialisation fails.
* Send UserRefreshEvent on user login and logout.
* Use godog v0.8.0 under new name 'cucumber' (instead of DATA-DOG).
