<pre>* SUMMARY
Improve Symbol() to string error message.
I'm not sure I agree with he "can't convert to a string" when Symbol().toString() at least provides a string. But still, our error message is super cryptic and needs to be improved.
* Safari
js> "" + Symbol()
TypeError: Type error
* Chrome
js> "" + Symbol()
TypeError: Cannot convert a Symbol value to a string
* Firefox
js> "" + Symbol()
TypeError: can't convert symbol to string
* Edge
js> "" + Symbol()
Object doesn't support property or method 'ToString'</pre>
