[REM] project: Remove the tasks merge feature

Purpose
=======

In a business point of view, it make no sense to merge record. if someone want really to merge record they have to do this manually to think about all corner case. What about id sent to the customer ? what about timesheet ? what about business ?

The idea of the task: remove this feature in both app, project.task and in helpdesk

Specification
=============

Remove both features

"Merge Selected Tickets" in helpdesk
"Merge Selected Tasks" in project.task
