[PATCH v3] emacs: Use the message cite variable instead of a calling cite-message-original directly

[Todd]

This fixes the test failure.  I didn't have dtach installed, so the
tests were being skipped earlier.  As to why the test fails, it
appears that the default for message-cite-function may depend on the
version of Emacs that you use.

This will likely cause notmuch replying to behave differently for
users if they upgrade, even if they don't customize
message-cite-function (in the case that it is not
message-cite-original).

Regarding the quotation changes in the test, it was not being
interpreted correctly without the double quotes.  I didn't look into
it in much depth, just fixed it for my case.

- Todd
