Month and day clear when entering era first time on iD

From #663:

🔴 The Start Date and End Date do not allow adding month and day, the entered values are cleaned when clicking out the field

@1ec5 asks:

I wonder if this is related to openstreetmap/iD#10145. Have we pulled in the fix in openstreetmap/iD#10151?

This is only on staging.

note that this appears to happen upon selecting AD/BC the first time I am editing the field:

@erictheise any update on this from your efforts on Friday?

I'm beginning to suspect this was introduced with OpenHistoricalMap/iD#193. start_date only has the year component by the time it returns from field.js which is what resets the input fields for month and day.
