Description

I was trying to test out the LFS support, I flipped LFS_START_SERVER to true and I got this:

2017/09/14 18:50:16 [...s/setting/setting.go:735 NewContext()] [E] Failed to create '': mkdir : The system cannot find the path specified.

Manually adding LFS_CONTENT_PATH = data/lfs to my app.ini makes it run as intended, updating the conf file with LFS_JWT_SECRET and booting up without issues.

It should either default to data/lfs (updating the app.ini) or quit with a descriptive error message.
