Can't apply a query to the master index

[maksymilian-majer]

I've tried applying query to the ref passed as argument to the NormalizedCollection and to the the NormalizedRef. In both cases I don't get any results.

Here are two plunks that illustrate this:

• Applying query to master index: http://plnkr.co/edit/max7TciVx48YG3cNcfpS
• Applying query to NormalizedRef: http://plnkr.co/edit/5AtkOtfvBorKkLnLCHAw

Because of this console error:

Error: Each argument to the NormalizedCollection constructor must be a valid Firebase reference or an Array containing a Firebase ref as the first argument

    at Object.NormalizedCollection (firebase-util.js:644)

This console error is in the first case and it's pretty clear that I can't apply query on the Firebase reference before passing it to the NormalizedCollection. I also tested applying query to the NormalizedRef which is returned by calling ref() on the NormalizedCollection. I concluded that it's possible from the docs (https://github.com/firebase/firebase-util/blob/master/src/NormalizedCollection/README.md#query-methods).

This is demonstrated here: http://plnkr.co/edit/5AtkOtfvBorKkLnLCHAw
You'll see in the console that on('value',...) results in null being logged to the console.

No disagreement here, just adding context with the console error.

In that case here's the console warning from firebase-util from the second example:

Hope this will be helpful.

Looks like this is because we call .child() on the query ref. Need to .ref().child() that.

I am trying to apply a query on the master index using the orderByValue() method however with the 0.2.4 release I am getting an 'undefined is not a function' error, http://plnkr.co/edit/HaA1lz
