[TECHNICAL-SUPPORT] Alarms/Announcements are not sent if display date is in the past 

Hi Jorge,

I'm sending this pull to you, because we couldn't find the responsible person for Announcements portlet.

First I tried to send it to Julio : https://github.com/juliocamarero/liferay-portal/pull/1655#issuecomment-16513553

Please review the changes.

Thanks,
Tamás
