Can you explain how this PR fixes the issue listed?

change line 340 in sd-webui-controlnet/internal_controlnet/external_code.py

from: script_args = list(p.script_args)
to: script_args = p.script_args_value

p.script_args returns None, which it not iterable to create a list (raises the error).
p.script_args_value returns a list with None objects, which seems to be fine so far

print (type(p.script_args))
print (p.script_args)
print (type(p.script_args_value))
print (p.script_args_value)

<class 'NoneType'>
None
<class 'list'>
[None, None, None, None]

I am wondering, according to https://github.com/AUTOMATIC1111/stable-diffusion-webui/blob/master/modules/processing.py#L256 p.script_args is the getter of p.script_args_value and I expect both return the same value but they don't.

My guess is, that somewhere p.script_args has been overwritten.
