[FIX] hr_timesheet: set 'My' filters at the top of the list in the search view

Steps to reproduce:
 - Install timesheets
 - click on all timesheets
 - open search view

Issue:
 - in search view 'my' filters block should be at the top of the list

Cause:
 - misplacing of the name month filter causes the issue.

Solution:
 - if we replace that filter below the group then the issue will be solved.
