Replace use by require.
Add require Koha::Calendar (seriously needed to prevent crashing).
Base expirationdate on today not on waitingdate (just as in Reserves).
Remove if ( waitingdate ) construction. Not needed anymore.
Remove $cancel_on_holidays. Not used. Note that the if construction around
the new pref is not strictly needed at upgrade time (pref still zero).
Fill the dbrev description.
