FIX: Avoid double-encoding featured topic title in user profile (#21507)

a373bf2 updated the behavior of replace-emoji so that the input is treated as unsafe-by-default. fancy_title is already escaped, so we need to mark it as html-safe to avoid it being double-escaped.

There is no need to html-safe the result of replace-emoji - it's already done as part of the helper.
