[pitivi] render: Always iterate on already available elements in encodebin

[Thibault Saunier <tsaunier src gnome org>]

    render: Always iterate on already available elements in encodebin
    
    Because if encodebin.profile.presence is > 0 then the elements are
    created right away exposing the pads and all.
    
    This makes sure that the encoders settings are taken into account!
