    Don't include traceback when wrapping exceptions

    The fix in fa52cb09b2270876c9d9a03106f961be6c9db834 strips tracebacks
    from exceptions when returning them to the user, but it still spams
    the log with a long traceback. We shouldn't be including the traceback
    when we wrap the exception in the first place. Instead we just
    include the message.

    It also updates the error code to 409 for device in use since this
    is actually a conflict.

    Fix for:

      bug 1155315
      bug 1103324
      bug 1092610
