[FIX] hr_recruitment: strip emails

- Create 2 applications with the following emails:
  'test@test.com'
  'test@test.com   '

The 'Applications' stat button doesn't match the 2 applications.

Since `_compute_application_count` uses a `read_group` for performance
reason, we choose to strip the value at create and write for the sake of
simplicity.
