[epiphany] Fix failed downloads to disconnect from the finished handler

[William Jon McCann <mccann src gnome org>]

commit 297c522463fb232ca23c6b1657fb3c2dd5aa526c

    Fix failed downloads to disconnect from the finished handler
    
    Otherwise the finished signal will be called right after the failed
    handler and the download's label will be set to finished instead
    of the error message.
