Fix crash in twig_template_get_attributes when input is not an array or object

This fixes a crash when the input of twig_template_get_attributes() is not an array or object, and strict mode is enabled.

Could you maybe place the exception tests in a different method?

This method already expects many of its inputs to cause an exception to be thrown (it tests getAttribute() in strict mode, and in many cases the attribute isn't defined). I don't see a real benefit from moving these tests in a separate method in this case.
