Unexpected error from pylint after upgrade to astroid 2.5.

[drfunjohn]

Steps to reproduce

astroid 2.5
pylint 2.6.0
elasticsearch 7.10.1
python 3.7.3

from elasticsearch import Elasticsearch
es = Elasticsearch(["test"])
es.indices.delete(index="test", ignore=[400, 404])

1. run pylint

Current behavior

line 3 >>> E1123: Unexpected keyword argument 'ignore' in method call (unexpected-keyword-arg)

Expected behavior

astroid 2.4.2: no error from pylint

I'm seeing similar 2.5-related issues with Enum subclasses. Particularly, Enum.__members__.items(). Pylint complains about __members__ have not member items which is incorrect.

With pylint 2.6.2, and astroid 2.4.2, everything is fine. With astroid 2.5:

(note lazy_object_proxy 1.5.2 is present)

@drfunjohn thanks for your report.
@chiefnoah and @limburgher can you open separate issues with a clear reproducer?
Thanks in advance

[limburgher]

Done, thanks! #897

[hippo91]

@drfunjohn i identified the faulty commit (cc3bfc5). I am looking for a patch.

[drfunjohn]

Wow, thanks for quick response.

[hippo91]

You are welcome but the patch seems tricky...
