Trello::Member API isn't returning emails

[zacharyliu]

Email addresses aren't getting returned in the API response to Trello::Member.find. There might be some missing permission.

This leads to some other subtle bugs, since User.from_trello tries to match the user by email address, which is the most accurate method. Since the email is missing, it has to try matching by full name or username, but some people's names don't match up. Normally users_from_card_data will update the User's trello_id to avoid this issue in the long term, but this never happens if a user never gets found in the first place. In the extreme case where none of the partners on a card match up, then CardSyncJob.users_from_card_data returns an empty array. And since [].present? == false, the sync job doesn't properly update the old list of partners.

this might be bc trello now requires each user to OAuth (instead of using an administrator API key) in order to get their email
