Fix argument ordering in migraton 056.
Fixes T138 and then some:
Include account_id in exceptions email,
Include errors in Monocle.

Summary:
To include account_id in the exceptions email, we simply use an extra account_id param;
I did some quick, prelim digging into directly using the account_id that the logger is initialized with
(through the event_dict passed to the structlog processors) but that seemed unnecessarily complicated.

The changes to include errors in Monocle should be more obvious;
we currently store the error in the database table itself because that's where Monocle pulls its data from but eventually,
we should move to a different approach.
Note that this rev includes a migration to change how we store sync_status info in models.account (switched to using a single JSON column)

Test Plan:
Visual app inspection.
Sync runs as before.
