[FIX] hr_holidays: resolve Missing Record traceback

Steps to reproduce (without demo data):
 - Install hr_holidays
 - Go to "My Profile"
 - Open "Time Off"

Issue:
  Accessing Time Off from a user profile triggers a `Missing Record` error.

Cause:
   The system was passing the user’s active_id to the employee record
   incorrectly.

Fix:
  Now, when the context's active_model is 'hr.employee', the correct
  active_id is applied.
