Emscripten: fix incorrect error check for WebGL context creation

Browse Source 
According to the documentation and testing the `emscripten_webgl_create_context` function returns `0` on error as oppposed to a negative number. This was causing the error message to be empty when the later `emscripten_webgl_make_context_current` call fails given the invalid context.

See https://emscripten.org/docs/api_reference/html5.h.html#c.emscripten_webgl_create_context
