fix: clear views on VideoAdapter's onBindViewHolder

Issue

• When scrolling horizontally on the feed, because we are using a recycler view and not resetting the image before a thumbnail is successfully loaded, the image from the view that was previously recycled shows up - The magnitude of this issue depends on the quality of the user's network - fast internet speeds minimize the problem - issue replication below:

What does this PR do?

• Resets the view before loading a new image to it;
