Summary:
I pretty shortsightedly made sending a side effect of save() in the case that a
server is configured for immediate sending. Move this out, make it explicit, and
get rid of all the tangles surrounding it.
The web tool now ignores the server setting and only repsects the checkbox,
which makes far more sense.
Test Plan:
Sent mails from Maniphest, Differential, and the web console. Also ran all the
unit tests. Verified headers from Maniphest.

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.
