Fixes #2590
Description
Reinitialize the enablement evaluator when the questionnaire response tree changes (i.e. repeated groups or items with nested questions are added or removed). This makes sure the pre-order list and parent tree are recreated to reflect the new tree structure of the questionnaire response, and that the question referenced in the enable when can be identified correctly.
Alternative(s) considered
I asked this question in FHIR chat https://chat.fhir.org/#narrow/stream/179266-fhirpath/topic/parent.28.29.20or.20siblings.28.29.3F and Paul and Brian suggested that we could use a variable defined at the parent of the repeated group. If this works in our case still needs to be verified.
