Data download gets an incorrectly written error

As discussed with @madprime, downloading data yielded an incorrectly written error.

Error:

TypeError: exceptions must be old-style classes or derived from BaseException, not str

this isn't raising the error correctly: https://github.com/OpenHumans/open-humans-api/blob/master/ohapi/utils_fs.py#L507

(Related to leading zero's being removed by excel when I opened a project metadata; I then copy/pasted into a .txt. Adding the missing leading zero's to usernames resolved the root issue)
