1.2.1

• BUGFIX: Context clearing should now work properly in DelayedJob and Sidekiq. Also, we properly clear context if Sentry causes an exception. [@nateberkopec, #520]
• BUGFIX: If Sentry will not send the event (due to environments or no DSN set), it will not attempt to "capture" (construct an event) [@nateberkopec, #518]
