Summary Don't nullify WebGLExtension::m_context on context loss.

WebGLExtension::loseParentContext() nulls m_context pointer. In the GPUP world, where any GL call can result in a context loss, this behaviour can lead to null pointer access at random places inside a WebGL extension object after the code has checked for a valid m_context pointer at function entry.
