unstable_batchedUpdates undefined, replaces batchUpdate function

[timkrins]

Ran into this issue when working through the react-treasurehunt example on Windows.

injectBatchingStrategy in Relay's GraphQLStoreChangeEmitter.js was for some reason being called with an undefined parameter, causing no updates to occur.

I might be linked to this issue here: facebook/relay#127, but I'm just beginning with Relay/Webpack and have no idea.

I fixed it in my own solution by checking if the function is defined before replacing it.

injectBatchingStrategy: function injectBatchingStrategy(batchStrategy) {
    if(typeof batchStrategy != 'undefined' )
    {
        batchUpdate = batchStrategy;
    }
},

Ah, my particular issue with Relay should be fixed in commit facebook/relay@2d82240

And fixed for good in facebook/relay@0c9725d! We'll get a new release out today.
