Pick the first correspondent if search returns multiple

[skius]

Currently, no correspondent is picked (undefined, to be precise) if the API correspondent search returns multiple results. This change simply picks the first result.

An alternative fix would be to check if the AI generated correspondent exists as a 1:1 match, and if not, force create it instead of picking from the existing list. For my documents there are generally too many correspondents being created and not too few, so I opted for the option in this PR to avoid even more.

Can you elaborate "Currently, no correspondent is picked (undefined, to be precise) if the API correspondent search returns multiple results. This change simply picks the first result."

You mean the paperless API right? I dont see a case where the exact correspondent could be existing 2 times in Paperless under 2 different correspondent objects.

I tried it right now, went into paperless, created the correspondent "Test", saved, create a new correspondent with "Test" -> error wont let me do that.

Or do you mean the OpenAI API? Never had this happend that it gave me multiple correspondents back.

@clusterzx: The paperless API is a substring search. If correspondents "AB" and "AC" exist, then a search for "A" will return both. This project seems to be aware of that in paperlessService, see:

paperless-ai/services/paperlessService.js

Lines 726 to 732 in 39a918d

	if (results.length > 1) {
	console.log(`[DEBUG] Multiple correspondents found:`);
	results.forEach(c => {
	console.log(`- ID: ${c.id}, Name: ${c.name}`);
	});
	return results;
	}

It's just that the downstream consumers of that method are not:

paperless-ai/services/paperlessService.js

Lines 755 to 761 in 39a918d

	const existingCorrespondent = await this.searchForExistingCorrespondent(name);
	console.log("[DEBUG] Response Correspondent Search: ", existingCorrespondent);
	if (existingCorrespondent) {
	console.log(`[DEBUG] Found existing correspondent "${name}" with ID ${existingCorrespondent.id}`);
	return existingCorrespondent;
	}

This PR fixes that and makes them Array-aware.

Oh true sorry, I did miss to implement this completly in all cases.
I thank you for the hint, but I will do it another style.

Next commit you can see the changes here and tell me what you think about it. Have to change some other things.

Thanks, looks good to me!
