Fix extract epoch from interval calculation

The new numeric code for extract epoch from interval accidentally
truncated the DAYS_PER_YEAR value to an integer, leading to results
that mismatched the floating-point interval_part calculations.

The commit a2da77cdb4661826482ebf2ddba1f953bc74afe4 that introduced
this actually contains the regression test change that this reverts.
I suppose this was missed at the time.
