getDropletInfo() does not return the assigned key(s)

[misterbayne]

I can successfully import an SSH Key and then I can successfully use that SSH Key to create a Droplet. I have verified that I can successfully log in to the Droplet using the SSH Key. However, when I use the DigitalOceanClient to getDropletInfo(), the keys field is always null. What has happened to the Key that was assigned to the Droplet on creation?
