Don't reuse response struct for multiple requests

A fix was added in ktrysmt#186 for the infinite loop while paging. The problem is that it didn't fix the underlying issue, and the fix actually breaks paging in certain circumstances. For example, if I have 13 repos, and a page size of 10, we'll do 13/10 = 1, which equals the page number of 1, and break without retrieving the second page).

The actual problem was that the `responsePaginated` variable was being reused in the loop, and the json decoder doesn't overwrite fields that aren't present in the response, so it was the `Next` field would end up with the value from the previous page, causing the same page to be requested forever.
