Don't ask for participant information when registering a team for an event.

Right now we're asking the purchaser to fill in a curler profile when they register a team. This has been causing confusion with some of our users who aren't actually *on* the team or participating themselves.

Here are the types of users registering a team that could be confused when we ask for participant information:

1. The coach.

2. Someone who's running the club they are representing. They may register multiple teams.

3. Parent, spouse, or other relative.

4. Other representative / assistant.

Instead we should just be asking for the team information and lineup.
