Although we had only 190 developers, the script
was accusing a total of 365 developers (with 188 inactive).
There were two problems here:
* The gitea API was only using the `limit` paramater when an explicit
page was passed.
* There was a bug with the get_next_page code, that would skip the last
page.
I now made the page always an explicit argument passed to fetch_single.
With this fix we now get: 190 developers with 98 inactive.
