[Bug] Timelogs in custom item type does only show my own timelogs

Hi there,

we identified a bug when it comes to custom item types in task.
Generally, you can see  the sum of time entries in tasks, which is very helpful to check, if all efforts has been fully booked. 

However, when you convert this task in a custom item type, on the same task 4h is shown instead of 56h. That's because a custom item type only shows my own time entries, but not the sum of all time entries. In the case, i booked 4 hours and my collegue 52h

Please fix that issue, this is very error-prone and can lead to a task/project being overbooked.
