[FIX] gamification: use right field on goal domain

There is no field 'ids' on a gamification.goal, but one called 'id'
Without this commit, calling _get_serialized_challenge_lines (or
indirectly, calling report_progress) with a non-empty subset_goals was
failing due to an invalid domain.
This is not supposed to happen on standard flow but can be triggered
with manual modification of date fields and refreshing a challenge.

Fixes odoo/odoo#25913

closes odoo/odoo#54363
