After Calling "finalize" on a "deposited" coin the client doesn't show an error/warning

[andreipope]

When the user calls finalize on a deposited coin, the client doesn't show a warning/error. Instead, it displays a message that can be mistaken as the outcome of a successful operation:

Finalized the exit for <coinId>

Should be solved by adding an event listener for Withdrew in https://github.com/loomnetwork/loom-js/blob/master/src/plasma-cash/entity.ts#L491
