"config" metadata on experiment is broken

[bfirsh]

Problem

This replicate.yaml:

repository: file://.replicate/

Produces this in the experiment metadata:

{"repository": "file:///private/var/folders/mf/qgf_gk717c1dfmy58rnsv2500000gn/T/tmpzybw7jt4/.replicate", "storage": ""}

It should be the same thing as what's in replicate.yaml.

Solution

When creating a project in project.go, it attempts to re-create a Config object. It should instead pass round the raw Config object so we can put that in the metadata.

It should also not include the deprecated storage option if it is blank.
