Avoid crashing in GetOldestSnapshot() if there are no known snapshots.
The sole caller expects NULL to be returned in such a case, so make
it so and document it.
Per reports from Andreas Seltenreich and Regina Obe. This doesn't
really fix their problem, as now their RETURNING queries will say
"ERROR: no known snapshots", but in any case this function should
not dump core in a reasonably-foreseeable situation.
