Fix Time#advance to work with dates before 1001-03-07
In #10634 the behavior of Time#advance was changed to maintain a
proleptic gregorian calendar for dates before calendar reform. However
it didn't full address dates a long time before calendar reform and
they gradually drift away from the proleptic calendar the further you
go back in time. Fix this by always converting the date to gregorian
before calling advance which sets the reform date to -infinity.
