[epiphany] If a tab is created only for a download, close it

[Gustavo Noronha Silva <gns src gnome org>]

commit 29c990d5a4662467e4708db1ab1cc06c4901fc7f

    If a tab is created only for a download, close it
    
    If a tab that has just been created ends up being just a download, then
    close it down. If it's the only one on the window, then make it show the
    overview instead.
