[Koha-patches] [PATCH] Bug 9211 - days_between wrong behaviour

[Tomas Cohen Arazi]

As noted in comments #15, #16 and #17 of bug 8486, and its API, Koha::Calendar->days_between
should always returns a positive number irrespective of the relative order of the parameters.
This is still an open bug, which arised when rewriting the Calendar.t file (Bug 9209).
