Unison breaks bin/doctor.sh script

[grayside]

In the Docker Machine functionality check, we get this error:

ERROR: Volume conditioner-sync declared as external, but could not be found. Please create the volume manually using `docker volume create --name=projectname-sync` and try again.

Note that the doctor script has been very minimally maintained and is likely not much used. A secondary contribution after this problem is fixed and any other lurking bugs cleaned up is a re-evaluation in how this is implemented and possibly adding a project script to run bin/doctor.sh and rig doctor to .outrigger.yml

$> bin/doctor.sh
