Handle negative view types properly in getScrapView

ListView had a bug where it would pass wrong view to
the adapter if adapter is using HEADER or IGNORE types
for views.

This CL fixes that issue and ensures that ListView
will not try to search scrap view lists for these
views which are never recycled.
