[BUG] in _send_private_request UnknownError: Media is unavailable

Hi!

First of all thank you @adw0rd for the great work!
During the use of the package I got the following error:

Traceback (most recent call last):

instagrapi.exceptions.UnknownError: Media is unavailable

I'am not sure if this is a real bug or not because I encountered this situation once. Maybe the user deleted the media?
Is it possible to check this before interaction?

[adw0rd]

The user may have deleted the post, or you have entered the wrong ID, or you have been banned by the user, or the user has a private profile

Thanks @adw0rd I just put an en extra check before any interaction for if the media still exists.
