[Python] external schemas each containing '#/parameter'

Description

I am combining several OpenAPI specifications, each of which has several external references. The generator reaches
all external references but mixes up one #/parameters in an external schema with one in a different external schema.

Swagger-codegen version

3.0.25

Swagger declaration file content or url

OpenApi 3 spec is a mashup of several, but the only two needed to reproduce the problem are:

• https://developers.exlibrisgroup.com/wp-content/uploads/alma/openapi/conf.json
• https://developers.exlibrisgroup.com/wp-content/uploads/alma/openapi/users.json

I will upload the combined spec once this issue is created, but see also https://github.com/NLM-OCCS/python-alma-sdk

Command line used for generation

java -jar lib/swagger-codegen-cli.jar generate -l python -c api-config.json -i target/spec.json --resolve-fully -o target

api-config.json has these contents:

{
  "packageName": "alma_api",
  "modelPackage": "models",
  "apiPackage": "apis"
}

Steps to reproduce

1. Create an environment with apache ant in the path
2. Clone from https://github.com/NLM-OCCS/python-alma-sdk
3. Bootstrap apache ivy by entering "ant bootstrap"
4. Build the spec and package by entering "ant build"

In the generated code, you can easily see the problem as follows:

grep Almawsv1confjobsjobIdParameter target/alma_api/models/*.py

For instance, the following should each be referencing Almawsv1usersParameter:

target/alma_api/models/user_role.py:        'parameter': 'list[Almawsv1confjobsjobIdParameter]'
target/alma_api/models/user_role.py:        :rtype: list[Almawsv1confjobsjobIdParameter]
target/alma_api/models/user_role.py:        :type: list[Almawsv1confjobsjobIdParameter]

Related issues/PRs

There is an salesforce issue reported to the vendor Ex Libris that I will separately update, and close.

Suggest a fix/enhancement

Unsure of the fix.

Clone NLM-OCCS/python-alma-sdk, bootstrap Ivy with ant bootstrap, then run ant build using the linked OpenAPI specifications and api-config.json. Inspect target/alma_api/models/user_role.py and the grep result for Almawsv1confjobsjobIdParameter; done means references from the users schema resolve to Almawsv1usersParameter rather than the conf schema parameter.
