Chat Webpath objects are not being parsed properly

[vcapelca]

Hi there! Thanks for creating this module, super helpful!

Today, though, there's been an issue when attempting to access the Chat Webpaths objects for some Chats. Basically, there's some chats where the Webpath list consists of a ProxyList rather than the usual Webpath object, which makes impossible to extract the different fields as used to:

>>> chat.webpath
[[1639008082, 'https://www.test.com', 'https://www.test.com', 'Test Title']]
>>> chat2.webpath
[Webpath(), Webpath()]
>>> [{'chat_id': chat.id, 'title': webpath.title} for webpath in chat.webpath]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 1, in <listcomp>
AttributeError: 'ProxyList' object has no attribute 'title'
>>> [{'chat_id': chat.id, 'title': webpath.title} for webpath in chat2.webpath]
[{'chat_id': '12345', 'title': 'Test Title'}, {'chat_id': '67890', 'title': 'Test Title'}]

I've applied a workaround to process these cases, assuming that the fields in the ProxyList always come in the same format:

if isinstance(webpath, Webpath)
            else {
                "chat_id": chat.id,
                "title": webpath[3],
                "to": webpath[1],
                "from": webpath[2],
                "timestamp": webpath[0],
            }

But thought it was worth sharing with you folks so a proper fix can be applied here, since the patch is quite hacky and I'd be expecting Webpath objects there, which seems to be something wrong when building the object on Zenpy side.

Best regards,
Víctor
