index.ts: fix double appending baseUrl when baseUrl does not contain host

By using axios.defaults.baseUrl correctly:
The idea is that you don't have to add it yourself anymore.
But for the empty root endpoint, we need to append
a / because axios supports the baseUrl, but not
using and empty string as the url for a request...?
