http: fix http client leaky with double response

[theanarkh]

Fixed: #60025

When a request corresponds to multiple responses, ensure that only the first one is processed and skip all subsequent invalid responses (or emit a response event then emit an error event on request object ?).

• make -j4 test (UNIX), or vcbuild test (Windows) passes
• tests and/or benchmarks are included
• documentation is changed or added
• commit message follows commit guidelines
