[Provider Model] Fix the NetworkDashboardFragmentTest failed issue

Since the getPreferenceScreenResId() is modified to return different resource ID when provider model enabled. So we need to update SEARCH_INDEX_DATA_PROVIDER class to match the same behavior.

Bug: 175290124
Test:
- Set Settings/System/Developer options/Feature
flags/settings_provider_model to true.
- atest -c NetworkDashboardFragmentTest
