Hi:

I am trying the latest changes in master and when I try to use any project-* command I always get an error:

```
project-current: Wrong type argument: listp, ~/projects/nanos_cluster/
```

Where ~/projects/nanos_cluster/ is actually the root of my current project

With this bt:

Debugger entered--Lisp error: (wrong-type-argument listp ~/projects/nanos_cluster/)  project--add-to-project-list-front((vc . "~/projects/nanos_cluster/"))  project-current(t)  project-switch-to-buffer()  funcall-interactively(project-switch-to-buffer)  call-interactively(project-switch-to-buffer nil nil)  command-execute(project-switch-to-buffer)

Do I need an extra setting/config or anything?
Best,Ergus
