bug thumbnails & make sort viewers number

[owengofficial]

sometimes double thumbnails appear this is very annoying please fix it, and also make it optional to sort the number of viewers from high to low and low to high (in popular tab) this is very important sometimes the number of viewers is random.

1. The issue with duplicate streams is likely because that is how Twitch is returning the data. We need to review it carefully and, if so, implement some extra verification.
2. The inconsistency in the order of viewers is because the stream viewers are not being shown together.
3. Sorting by views is already implemented.
