Previous cleanups (mostly the removals of Python __future__ imports) were done in a way that introduced leading newlines. Delete leading newlines from all files, except static/assets/zulip-emoji/NOTICE, which is a verbatim copy of the Apache 2.0 license. Signed-off-by: Anders Kaseorg <anders@zulipchat.com>
