Bug 15149: Serial test prediction pattern does not consider end date

Bug 15149: Serial test prediction pattern does not consider end date

To reproduce:

1) add a serial.
2) set first issue = today
3) set frequency = 1/month
4) dont set subscription length
5) set subscription start date = today
6) set subscription start date = today + 1 year
7) set numbering pattern = Number
8) test prediction pattern.
=> Without patch : you will get a list of 1000 issues, going well beyond subscripton end date.
=> With patch : shows only the issues within the date range.
