Subject: [PATCH] Revert "write_records_to_tsv: Stop quoting output TSV"

This reverts commit 915672e9db021588349ede4e23f21003455eb705.

Per discussion in <https://github.com/nextstrain/augur/pull/1563#discussion_r1699260164>,
keep CSV-like TSV where quotes may be added or removed, but parsed
values should be equivalent.
