Array max notifications feature does not work

[Neil Munday]

In the existing code (version 4.8 and below), the check for limiting the number of e-mails notifications for job arrays is:

if not array_summary and 0 < options.array_max_notifications > len(jobs):

This is incorrect and should be:

if not array_summary and 0 < options.array_max_notifications < len(jobs):

Fix merged into main.
