Random 'synthetic events' error

[emilyb7]

Since refactoring some of the sockets stuff yesterday, this error message has been appearing somewhat sporadically.

Full error message:

main.js:4827 Warning: This synthetic event is reused for performance reasons. If you're seeing this, you're accessing the method `currentTarget` on a released/nullified synthetic event. This is a no-op function. If you must keep the original synthetic event around, use event.persist(). See https://fb.me/react-event-pooling for more information.

I don't really understand the docs it points to and how they are relevant to us.

In the meantime, nothing appears to be actually broken.

@shiryz @des-des @MHemsley any idea if this is bad?
