    do not flush selection on "old" boot source

    This fixes an issue introduced by watchers:
    when page initialized images watchers called before
    select boot source watcher.it leads to sutiation when
    we specify selection from user input and flush it on
    updateBootSource. as a result page come to
    inconsistent state described in the bug.
    Perhaps, this requires big refactoring but in the
    current patch we do not flush selection if boot type
    was not changed. it allows to use image, snapshot,
    volume from context as ctrl.selection.
