Symbol action may convert failed in saga

[purepennons]

I modified the saga-counter example to use Symbol action instead.

And when I triggered multi times (maybe fast), the devtool caught all the actions, but some of them were converted failed.

const composeEnhancers = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__({ serialize: true }) || compose;

export const INCREMENT = Symbol('INCREMENT')
export const INCREMENT_IF_ODD = Symbol('INCREMENT_IF_ODD')
export const INCREMENT_ASYNC = Symbol('INCREMENT_ASYNC')
export const DECREMENT = Symbol('DECREMENT')

It was downgraded and fixed in 2.16, which will land in a day on Chrome Store.
