Pass original response items instead of copy to getEnabledResponses

IMPORTANT: All PRs must be linked to an issue (except for extremely trivial and straightforward changes).

Fixes #1776

Description
In getQuestionnaireResponse we are passing the questionnaire response items of the copy of the quesitonnaireResponse and in the EnablementEvaluator we create the questionnaireResponseItemPreOrderList and questionnaireResponseItemParentMap from the questionnaireResponse. This would result in itemIndex = -1 for all indexOf search, since we are trying to search for objects in the original list whereas the list item that is being searched for is part of the copy list.
The code change is to pass [email protected] . This will search for items in the original list and the enablementEvaluator will work as expected

ok so i think the root cause of this bug is actually here:

android-fhir/datacapture/src/main/java/com/google/android/fhir/datacapture/QuestionnaireViewModel.kt

Line 634 in 854c23c

val enablementEvaluator = EnablementEvaluator(questionnaireResponse)

where we are creating the enablement evaluator from the questionnaire response in the view model.

this kinda means that the current interface (if we see it as an internal/private interface) of getEnabledResponseItems is kinda broken. it only works if questionnaire response items passed to it belong to the questionnaire response in the view model.

maybe create another wrapper function in which you create the evaluator and then make the current function take an enablement evaluator with the condition that it is created from the same questionnaire response?

see comment.

also would be excellent if we have a test case that can catch this.
