Unban clients when they are focused

In commit 3dbf89c I removed a client_unban() in the code path for focusing
clients. The idea was that client focusing is now done after rebanning, so that
it should already be visible by the time this code is executed.

However, minimized clients obviously don't get unbanned, So we have to call
client_unban() here to make sure the client is unminimized.
