[BUG] tasks with multiple alarms do not alert

[itsbrody]

Describe the bug
First "seen" on a task with sub tasks, where I manually set the alarm(s) to the date/time where I wanted to be reminded to do the sub task. Later on seen also on tasks, which alerted (having one alarm) and I decided to postpone the task (in the alarm box) by one day. Then the task have two alarms inside and does not alarm anymore.

To Reproduce
(1) Create a task and inside an alarm. Await the alert dialog.
(1b) add then another alarm on that task
(1c) the second alarm will not occur

(2) having an task with an alarm set. Awaiting the alert dialog.
(2b) select to postpone the task
(2c) check the task that it now have two alarms inside
(2d) the second alarm will not occur

when you remove (between 1b and 1c) or between (2c and 2d) past alarms that there is only one alarm inside, this one will occur at that alarm time.

Expected behavior
Any listed alarm should be issued by the system.
