[FIX] hr_holidays: leaves_count on stat button only counts type 'remove'

The stat button 'Leaves' on the employee's form view displays the total number
of leaves (including holidays allocations and leave requests). When the button
is clicked, only leave requests are show, which makes inconsistent the number
displayed with the list of results. This fixes this behavior.
