Remove AccountDropdownMini component

The `AccountDropdownMini` component featured the ability to switch
accounts using a dropdown, but this functionality was disabled in MetaMask#6024.
It has been acting as a restyled `AccountListItem` since then.

The component has been removed, and the style changes moved to the sole
parent component (`RequestSignature`).
