OK, what happens if you now select the bottom item, click on "Unmount", and then try to empty the trash?
I don't know the mechanics, but something is obviously connecting with that .dmg, so trashing it may solve your problem.
Let's see.
Edit: I'm gonna guess that there's still some aspect of Evernote left on your Mac that's smart enough to recognize that the .dmg is still there and ask you to install the app so it can use it.
