todo list errors out when no context folder exists yet

[nextuponstream]

this is common after creating a new context. When issuing todo list, this error shows up:

IO error for operation on /home/user/Documents/todos/new-context: No such file or directory (os error 2)
Error: Custom { kind: Other, error: Error { depth: 0, inner: Io { path: Some("/home/user/Documents/todos/new-context"), err: Os { code: 2, kind: NotFound, message: "No such file or directory" } } } }
