will f0e32ae0c1 calendar: fix transferred candidates blindly winning outright
Found via real data (the May sanctoral pull): a transfer landing on a day
whose own native winner was temporal blindly took over as winner,
regardless of that day's own precedence category — so a transferred-in
Simplex saint (St. Felix I, impeded by Pentecost's Ember Saturday) was
overwriting Trinity Sunday itself instead of being merely commemorated,
the way a native Simplex candidate on an ordinary Sunday already
correctly is.

Fixes applyIncomingTransfer to run the arriving candidate through
decideOccurrence using the receiving day's own temporalCategory, the same
rules a native occurrence there would use, instead of assuming an empty
temporal slot means automatic victory.
