[FIX] website_event: copy template question translations

Versions:
---------
- 15.0+

Steps to reproduce:
-------------------
1. Have multiple languages and Studio enabled;
2. create an event template;
3. add a question;
4. add translation to question;
5. use template to create event.

Issue:
------
Translation doesn't get copied from template to event.

Cause:
------
The `_compute_question_ids` method copied the questions by *manually*
recreating them. It didn't use the `copy_translations` method like the
regular `copy` methods does.

The reason the questions were recreated is because question records
cannot link directly from event template to event, as changes to the
event shouldn't affect the template.

Solution:
---------
Use the `copy` method instead while setting `event_type_id` to `False`
to satisfy the restriction.
