getStickerSet returns a Chat object for getResult

[Taeir]

Problem:
When using $response = Request::getStickerSet($data);, $response->getResult() returns a Chat object (Entity), instead of the intended StickerSet object (Entity). This makes getStickerSet unusable.

Cause:
StickerSet has a title field. ServerResponse interprets anything with a title field as a Chat object.

Fix:
Add a line to interpret something with the field stickers as a StickerSet, above the line for title.

Relevant code:

core/src/Entities/ServerResponse.php

Line 116 in 7b5bf5f

'title' => 'Chat', //Response from getChat

I will create a pull request to fix this in a bit.
