[epiphany] embed-shell: Use g_signal_connect_object everywhere

[Michael Catanzaro <mcatanzaro src gnome org>]

commit 1a97de9759b63e6e7896799706c88aa43de236b6

    embed-shell: Use g_signal_connect_object everywhere
    
    Change the remaining occurrences of g_signal_connect() to use
    g_signal_connect_object() instead, which ensure that the EphyShell
    instance will not be destroyed while signal handlers are being
    executed.
