SubQuestionnaire does not open within SubQuestionnaire

[mlaletina95]

Description:
The subQuestionnaire feature does not work when nesting one subQuestionnaire within another subQuestionnaire.
When trying to open a subQuestionnaire inside another subQuestionnaire, the system fails to load the nested
subQuestionnaire properly.

Steps to Reproduce:

1. Create a parent Questionnaire with a subQuestionnaire reference.
2. Nest a second Questionnaire inside the parent as a subQuestionnaire.
3. Try to open or access the nested subQuestionnaire.
