Subject: [PATCH] [CLEANUP] http_server_error() must not purge a previous
 pending response

This can cause parts of responses to be truncated in case of
pipelined requests if the second request generates an error
before the first request is completely flushed.

(cherry picked from commit d5fd51c75be6479539228f84377622a986b23be2)
