fix github api url (#794)

## What
previously, when an account `csdpSettings` would contain apiUrl of
`https://api.github.com`, the token validation check would call
`https://api.github.com/api/v3`.

i fixed the githubProvider code to check for "github.com" in the
hostname, and if it exists - to not add any `/api/v3` path to the base
url at all.

## Why
i guess `https://api.github.com/api/v3` use to work, but recently github
changed their side, and now it returns 404.
