Always list the day's actual winner first in getDayLabel

The anchor-day and plain-temporal-fallback branches were listing any
commemorated saint before the winning identity, so a lower-ranked saint
merely riding along as a commemoration (e.g. St. Andrew on Advent I, or
Ss. Tryphon/Respicius/Nympha on an ordinary Sunday) read as if it were
the day's own winner, with the actual winner's rank label dangling at
the end with no name attached. The winner should always lead.
