Emacs: Notmuch logo is not displayed when using ELPA package

[Jinwoo Lee]

I mistakenly sent from a wrong account.  Sending again...

----------

TIL notmuch shows a logo at the top of the Emacs buffer!

I've been using the ELPA package so far and it didn't show the logo.  I
switched to my local git repo to test my changes and realized that we
have a logo!

Anyone know why the ELPA package wouldn't show it?
