Use one Glide instance per NewsListRecyclerAdapter

[Unpublished]

Fixes the issue mentioned in #1405 without each view having its own glide instance

Also fixes leaking context via static reference to FavIconHolder

Ref: #1405 (comment)
I think the main culprit is having a static FavIconHandler which leaks context.

Using a per fragment instance approach for Glide will still benefit from Glide's lifecycle awareness, pausing requests of not visible fragments. Also fragments context should be aware of configuration changes like theme AFAIK.

@DoHe Can you double check if this branch fixes the issue for you as well?

@Unpublished yes, I can confirm this fixes the favion issues I was seeing 👍

@Unpublished Thank you for implementing this so quickly! Looks like a great solution to me. I'm glad that you were able to remove the static reference.
