Always check if the view can be recycled.

Previously, the recycling was only checked for multiple layout, as it
was assumed the AppWidgetHostView would make the basic check. However,
adapters views (e.g. ListView, ...) do not make any recycling check,
instead relying on caching using the Layout id. The caching cannot be
changed as it is common to other parts of Android.

This CL ensures the view can be recycled when reapplied, always.
