revsets: preserve ordering with the or operator

This is valuable because now revsets like 'bookmarks() or tip' will
always show tip after bookmarks unless tip was itself a bookmark. This
is a somewhat contrived example, but this behavior is useful for
"where am I" type aliases that use log and revsets.
