Log errors to DevTools console from executeScriptAsync

[ukandrewc]

Would be really good to see errors logged when calling executeScriptAsync.
I'm moving to WebView from GeckoFX, where any script execute errors are logged.
As you can imagine, it's really useful when you call
result = await executeScriptAsync("myJS('test')")
and nothing is returned because myJS has an error.
