#940: Use correct component IDs when extracting analysis date

The component ID was being used to create a map of analysis dates to
items, but the Pull Request's component ID did not map into this item,
so the Pull Request web service was always returning the analysis date
as empty. The service has been altered to use the root component ID as
was used in the search to ensure the IDs align.
