Error on get_chat caused by pinned messages

Checklist

• I am sure the error is coming from Pyrogram's code and not elsewhere
• I have searched in the issue tracker for similar bug reports, including closed ones
• I ran pip3 install -U https://github.com/pyrogram/pyrogram/archive/master.zip and reproduced the issue using the latest development version

Description

I found a single chat where the pinned messages has, for some reason unknown to me, a wrong id.

The problem is that, for that reason I'm unable to interact with the chat. It is possible to use a try except block for the pinned message retrieval?

Steps to reproduce

I simply get this error using the get chat on a chat called "vezzoblog". Up until now it's the only chat i had this problem

Code example

from pyrogram import Client

app=Client(...)

with app:
        app.get_chat("vezzoblog")
