[PATCH (GIT-GUI)] git-gui: Fix the search bar destruction handler.

Since delete_this is an ordinary function, it
should not be passed to cb; otherwise it produces
errors when blame windows are closed. Unfortunately,
it is not noticeable when blame is shown in the
master window, so I missed this bug.
