revlog: choose a consistent ancestor when there's a tie

Previously, we chose a rev based on numeric ordering, which could
cause "the same merge" in topologically identical but numerically
different repos to choose different merge bases.

We now choose the lexically least node; this is stable across
different revlog orderings.
