test/http: decrease test runs from 20 to 3 to decrease test time

Multiple HTTP requests are sent in parallel. Processing of the responses are done
asynchronously in the main thread. The test should ensure that there is no double
free, memleak, mix-up of content, ... for multiple parallel requests.
Fixes #1211 slow https test.
