Handle width and height placeholders in the thumbnail URL

[Makrit]

Proposed change

The Twitch API does not work with the placeholders {width} and {height} still present in the URL.
The API accepts both values set as empty strings, and interprets this as a request for the maximum resolution image. Therefore we modify ".../username-{width}x{height}.jpg" into ".../username-x.jpg", in order to avoid an error.

One query. Also, ideally a test should be added to verify correct behavior.
