Title: Fix node removal

Fixes removal of glam node non-existent node from Viewer. Here's an example
```html

```
Say I want to move testGroup to scene0, but scene1 was never parsed by glam.
```javascript
var scene = document.querySelector('#scene0');
var group = document.querySelector('#testGroup');
scene.appendChild(group);
```
This used to fail as it attempted to remove `testGroup.glam.obj` from the `Viewer` in `glam.Viewer.prototype.removeNode` , where `glam` (and thus `obj`) is undefined as it was never added.
