Get User Emotes has empty emote set id when no broadcaster_id parameter is provided

[tduva]

Brief description
When no broadcaster_id is provided only very few emotes returned have the emote_set_id field filled.

How to reproduce
Request https://api.twitch.tv/helix/chat/emotes/user?user_id=<user_id> and fewer emotes will have emote_set_id filled than with the broadcaster_id parameter.

Expected behavior
All emotes should have the emote_set_id filled, or at least it shouldn't depend on the broadcaster_id parameter.

Is this occurring for emotes that should have an emote_set_id filled in? Can you provide an example of this occurring when calling the API?
