[Bug]: Issues with automated model id appending to the filename

[Lumerica]

Describe the bug.

There are several issues with the automatic appending of model ID in the filename.

First issue:
If you have already downloaded the model previously (with no model id) and try to lookup the same model. you will see that the filename suddenly shows up as if you have downloaded the file before with the model ID appended.

Second issue and most critical:
The appended model id is incorrect, I haven't encountered a situation where it appends a correct model id. it appends a totally different random model ID. it is not the model ID nor the model version ID.

Ps. I think it should be an option rather than forcing it to be appended

Steps to reproduce the problem.

For first issue, just search for a model you have downloaded already without the model id
and you will see that it shows a model id appended in the filename within the extension.

2nd issue is, you just copy whatever model id the extension is showing and append it the the link "https://civitai.com/models/" as suffix open that link you will notice that the model likely unrelated to the said model.

Expected behavior

For first issue, it should show what is the actual filename instead of appending the model id
