[epiphany] Unify all web context setup in EphyEmbedShell on primary instance startup

[Carlos Garcia Campos <carlosgc src gnome org>]

commit efccc1eac4ac4e15fd4f5695d27a85c7d25c3cc6
Author: Carlos Garcia Campos <cgarcia igalia com>
Date:   Thu Mar 28 15:56:23 2013 +0100

    Unify all web context setup in EphyEmbedShell on primary instance startup
    
    Cookies, web extension and custom URI handlers were initialized in
    ephy_embed_shell_init(), so they were always called even for secondary
    instances. All other initializations were in ephy_shell_startup so that
    it only happens for the primary instance. Move all the code to
    ephy_embed_shell_startup to make sure everything happens at the same
    time and only for the primary instance.
