Missing ssh key in docker authorized keys file should produce an error rather than falling back to asking for root password

[joachim-n]

I was following the instructions in the README for the occhio project and was doing this:

~/Sites/multibasebox/projects/occhio-cms-be joachim$ phab -cmbb install

 Install new database for configuration `mbb`? (yes/no) [no]:
 > yes

 // Installing new app for `mbb`

root@occhio-cms-be.test's password:

The problem was actually that my SSH key was missing from the docker authorized keys file.

The command should exit with an error rather than falling back to asking for a root password.
