scripts/send-pull-request: Avoid multiple chain headers
When creating a patch set with cover letter using the send-pull-request script, both the "In-Reply-To" and "References" headers are appended twice in patch 2 and subsequent. That's because git-format-patch already inserted them and then git-send-email repeats that. Suppressing mail threading in git-send-email with --no-thread avoids the problem and is the right solution because it works regardless whether git-send-email is called once or twicee. Repeating these headers is a violation of RFC 2822 and can confuse mail programs. For example, Patchwork does not detect a patch series problem when there are these extra headers.
