The create-session-form was calling startInstance() without passing the
selected config profile and SSH keys. This caused the backend to receive
ssh_key_ids=[] and clear the keys that were stored during createInstance.
The .ssh directory was never mounted because instance.ssh_key_ids was
wiped during the start call.
Also includes minor formatting cleanup on the data migration.
