    DVR: make sure snat portion is always scheduled when needed

    commit 236e408272bcb9b8e957524864e571b5afdc4623 introduced
    a regression where if router without external gateway was already
    scheduled to all dvr_snat agents, then when adding external gateway
    to the router, snat portion scheduling was skipped.
    The patch fixes regression and adds corresponding unit (functional
    in fact) test.
