    gkr: Fix a crash for some Epiphany passwords
    
    The NULL-check in `GkrItem.epiphany_custom()` checked the wrong
    variable, making it possible that we were still passing on a NULL string
    as a username to `GLib.Markup.escape_text()`
    
    Fixes https://gitlab.gnome.org/GNOME/seahorse/issues/225
