Bug 23382: Truncate dates to minutes for comparison.

Bug 23382: Truncate dates to minutes for comparison.

It's somewhat of a mess in C4::Circulation as to when dates are
truncated and when they are not and as such Koha::Charges::Fees could
not reliably assume that the dates passed in were consistent with each
other. As such, we take the approach of always truncating to the
greatest minute smaller than the passed in dates so we are comparing
like for like.
