Get a reminder of all notes at 4PM

[jonfazzaro]

As a user who has written notes,
I want to get a reminder of all of my notes at 4PM,
So that I can be jolted into time-logging action with a brain full of things to log.

Given the user has not written any notes,
When the reminder runs,
Then the system does not send any messages to the user.

Given the user has written notes,
When the reminder runs,
Then the system sends a message to the user that contains all of their notes.
