WebGLRenderer.setExtensions is a new method that queries the GL context to get the list of supported extensions. Which it then sets into the class properties. This method is called internally as part of the init and restore process.

When the WebGL context was restored it would incorrectly try to call `init.setupExtensions()` which didn't exist. It now calls the correct method, `WebGLRenderer.setExtensions`. Fix #6905
