    wizard: Unset collection source on main page
    
    Instead of unsetting collection source just before preparing for a URI,
    we now do it each time user goes to main page of wizard source. With
    former approach, we don't unset collection source if user first enters
    URI manually, changes his/her mind at 'Review', goes back to 'Source' and
    chooses a ready media on the main page.
