new client 2017 09 19 various fixes: subscriptions, streaks, etc (#9047)

* remove excess brace on settings > subscription screen

* prevent User icon > Settings > Subscription page from crashing when subscription has termination date

* stop subscription modal from pitching subscription to a subscriber

* change placeholder text from Username to Login Name for consistency with other login/register forms
