Collision using unloaded asset bug

[ma-vejsada]

Description

Collision component throws an error when using unloaded render asset. Black screen will appear and project could not be launched.

Shortened error:

TypeError: meshes is null
    createPhysicalShape https://launch.playcanvas.com/editor/scene/js/engine/playcanvas.dbg.js?version=1.51.6:51339
    doRecreatePhysicalShape https://launch.playcanvas.com/editor/scene/js/engine/playcanvas.dbg.js?version=1.51.6:51398
    loadAsset https://launch.playcanvas.com/editor/scene/js/engine/playcanvas.dbg.js?version=1.51.6:51377
    ...

Steps to Reproduce

1. import custom model (as render asset, with hierarchy)
2. uncheck preloading (both template and render)
3. create collision component on empty gameobject
4. assign imported render asset to collision component
5. launch project
6. this error appears

Possible solution

1. Implement asset resource check.
2. Implement asset awaiter, to wait until asset is loaded, then use the mesh.
