genlist: Fix fileselector crazy behaviour

When using the fileselector in tree view mode (ie. expandable),
expanding any folder with a lot of files in it would cause the
genlist view to jump somewhere to the bottom. This is because
the mechanism preventing the view from moving was assuming that
all "prepend" operations meant prepending before the selected
item. This is not the case in case of expansion like in the
fileselector.
