Drew Regitsky f1d3959591 fix(send): make send/syncback draft tasks cooperate, fix task ordering tracking
Summary:
Fixes an issue with sending where certain conditions could result in a
duplicated message.

Fixes task dependency logic for draft syncback and send. Changes `createdAt`
on tasks to instead be `sequentialId`, assigned when the task is queued, to
track order of enqueueing. Renames `isDependentTask` => `isDependentOnTask`
and adds comments for clarity.

Test Plan:
Specs updated. Might be good to add some later to test this particular
edge case.
