FIX: poll ranked choice results not showing on first vote (#28542)

Browse Source 
Currently (for Ranked Choice only) a javascript exception is raised on very first vote, preventing the results from being rendered requiring a browser refresh (which doesn't error).

Resolves: TypeError: this.args.rankedChoiceOutcome.round_activity is undefined with simple addition of optional chaining operator.
