Project name cannot be inferred when loading PEP from csv

This would be a separate bug, then, because those are valid projects.

Currently, in Peppy, this will search for the name field in the project config. If none is given, it will default to project as the name.
However, with loading from a csv, there is no project config and Peppy raises a NotImplementedError:
