dp-cli fails to run on fresh setup

[tomakado]

If I run dp-cli on fresh machine, I get:

Error loading config: open /Users/tomakado/.config/dp-cli/config.json: no such file or directoryToolkit for managing Defer Panic articles and other stuff

Also, after I've written default(!) value to config's server key, I'm not able to log in:

➜ dp-cli login
panic: runtime error: invalid memory address or nil pointer dereference
