epriestley 72e33c9e5a Fix a threading issue with Amazon SES
Summary:
Amazon SES does not allow us to set a Message-ID header, which means
that threads are incorrect in Mail.app (and presumably other applications
which respect In-Reply-To and References) because the initial email does not
have anything which attaches it to the rest of the thread. To fix this, never
rely on Message-ID if the mailer doesn't support Message-ID.

(In the Amazon SES case, Amazon generates its own Message-ID which we can't
know ahead of time).

I additionally used all the Lisk isolation from the other tests to make this
testable and wrote tests for it.

I also moved the idea of a thread ID lower in the stack and out of
DifferentialMail, which should not be responsible for implementation details.

NOTE: If you push this, it will cause a one-time break of threading for
everyone using Outlook since I've changed the seed for generating Thread-Index.
I feel like this is okay to avoid introducing more complexity here.

Test Plan:
Created and then updated a revision, messages delivered over Amazon
SES threaded correctly in Mail.app. Verified headers. Unit tests.
