fix(randomizer): Initialize RANDOMIZER_CONFIG widget with default config

Initialize internalValue with default RandomizerConfig object instead of
undefined to prevent frontend from sending empty string to backend when
widget is first created.

This fixes the 'str' object has no attribute 'get' error that occurred
when running a newly created Lora Randomizer node before any user
interaction.

Fixes #4
