Fix problem of having the wrong window selected after saving foo.gpg

* lisp/epa.el (epa--select-keys): Restore the window configuration
after selecting the key to use (bug#43703).  This also ensures
that the buffer we were editing ends up as the current buffer
after saving it, instead of selecting a different window.
