We just copy the existing contents of EditAvatar and paste into EditUserAvatar and EditThreadAvatar and update imports.
In subsequent diffs we will:
- Move UserAvatar and ThreadAvatar "into" EditUserAvatar and EditThreadAvatar respectively instead of passing in React.Node prop.
- Pull out common functionality to hooks
- Introduce user/avatar-specific functionality
- Once everything is working, consider introducing some sort of BaseEditAvatar with some of the common styling/layout stuff (eg pencil icon). Defer this until the end once we have everything working.
