Temporary fix for the issue in Contacts that makes the wrong photo to be shown.

The issue appears to have something to do with extensive
concurrency going on there. For now I am just shrinking
the thread pool to one thread and that seems to be addressing
the problem.  Next step will be to redesign the photo loading.
