[ENHANCEMENT] Use league specific avatar before defaulting to sleeper profile avatar

[goingthisway]

Is your feature request related to a problem? Please describe.
If a user does not have a sleeper profile pic, the website shows a null picture.

Describe the solution you'd like
By replacing the avatar fetch with an if statement that tries to use the team picture before defaulting to the profile picture, we can avoid null picture

Code Change:
Replace https://sleepercdn.com/avatars/thumbs/${user.avatar}
With

user.metadata.avatar ? user.metadata.avatar : `https://sleepercdn.com/avatars/thumbs/${user.avatar}`

Lumping this in to the upcoming update. Should be released in the next week or two!
