BingMapsGeocoderService crashes since Cesium 1.49

[SunBlack]

Since Cesium 1.45 BingMapsGeocoderService is no longer the default geocoding service. In changelog following changes are recommend in case you want still use it

Cesium.BingMapsApi.defaultKey = 'yourBingKey';
var viewer = new Cesium.Viewer('cesiumContainer', {
    imageryProvider : new Cesium.BingMapsImageryProvider({
        url : 'https://dev.virtualearth.net'
    }),
    geocoder : [
            new Cesium.CartographicGeocoderService(),
            new Cesium.BingMapsGeocoderService()
    ]
});

This works fine until Cesium 1.48. But with 1.49 & 1.50 you got following error with this if you search for a city:

An error occurred while rendering. Rendering has stopped.
RangeError: Invalid array length

I can confirm this crash. Looks like you don't even need to change anything, it even happens in the Hello World.html. All you have to be doing is using the Build/Cesium.js. It doesn't happen in the Unminified version.

So far I've narrowed it to down updateFrustums in View.js. It seems that near, far, and numFrustums are passed in a NaN. I'm not sure why yet this would only be the case using the built version.

This also came up on the forum.

@lilleyse @bagnell there seems to be an influx of camera related NaN crashes. Did something change in the last two releases?

[bagnell]

There were a few changes for the 1.49 and 1.50 releases but it was mostly reorganizing code. Nothing jumped out at me that would be causing an issue.

@mramato do you think this could be related to your geocoder fly to changes?

[mramato]

Yes, this has nothing directly to do with Bing, it's just getting triggered by their results. I'll open a PR as soon as I get a chance.

Also added next release flag so I don't forget.
