Currently when you upload an image as an avatar, the "SELECT FILE" button disappears and you get another button to use the uploaded file. However, if you didn't like how the uploaded image looks you cannot upload another one. The work around is to reopen the avatar settings page, instead the upload button should stay there to allow the user to upload a different image.

Removed the trash icon since the buttons are used to upload files and not delete them
