null is not an instance of stdClass

[lausek]

Client->getUpdate() could return null through json_decode which leads to this fatal error:

Fatal error: Uncaught TypeError: Return value of TuriBot\Client::getUpdate() must be 
an instance of stdClass, null returned in turibot/src/Client.php:46

PHP version: 7.3.13
Possible solution: Add nullable or remove type hint

I could do a fix as you say, but the problem would remain, it should not return null.
Can you understand why the json decode goes wrong?
You may have this problem
If you can, see with json_last_error what error it gives you

No, I'm just calling the hook by myself so the input stream is empty. Anyways, the function should not panic.

What would be the value of getUpdate if the decoding wasn't successful?

The return value of getUpdate could simply be a null, what do you think about it?

Yeah, think so too. That's why I created a pull request.
