TypeError: ArrayUtils.GetFirstElement is not a function

• Operating system: macos v10.14.1

• Browser: chromium v70.0.3535.0

Description

I've been using Group class as a pool of alive / dead objects but since i'm using multiple cameras in one scene I thought the Container might be a better choice, so I've tried it - replaced getFirstDead with getFirst("active", false) and got the following error:

Uncaught TypeError: ArrayUtils.GetFirstElement is not a function
    at Container.getFirst (Container.js:613)
    ...

It looks like GetFirstElementhas been renamed to GetFirst.
Did a search on the repo and found only two occurrences but not the source.

Example Test Code

The following crashes:

const c = new Phaser.GameObjects.Container(scene);
...
c.getFirst("active", false); // throws an error

The following works: (taken from Container#getFirst)

Phaser.Utils.Array.GetFirst(c.list, "active", false);
