Printing from two apps at the same time not working.

When printing from two apps at the same time the second print UI is
getting stuck. There were a couple of issues here:

AdapterView was not notifying for item selection if the data changes
after scheduling a dalayed selection notification and the notification
execution. The code assumed that a layout pass will occur and posponed
the notification after the layout pass but it is not guaranteed that
such a layout pass will occur. Now we delay only if a layout pass is
being scheduled.

Also when binding to the PDF rendering service the print spooler was
using the same intent and as a result two print activites were getting
the same renderer instance while they should get separate ones. Now
we use different data in the intent to ensure we get separate renderer
instances.
