* fix: custom converter should not use Handle
* fix: no more need to check if icon is empty
It was a bug that the Handle<NativeImage> can be non-empty when the
image file does not exist. The bug was caused by the converter code
writing out the image even when the convertion fails.
The bug was work-arounded by adding an additional check, but since the
original bug had been fixed, the additional check is no longer needed.
