Fix #1609, fix #1628 - Revert #1397 (#1700)

When transmitting data in a HTML-encoded element like <content type="html" />,
relying on newlines being preserved is not wise, since HTML by itself
does not care for newlines - it cares for <p> and <br>

Additional fix: reset NSFW toggle after sending toot
