Fixes unit tests to clean up temporary directories

This patch fixes the unit tests to remove the temporary directories
created during run of unit tests. Some of unit tests did not tear down
correctly, whatever it had set it up for running. This would over period
of time bloat up the tmp directory. As on date, there were around 49 tmp
directories left uncleared per round of unit tests. This patch fixes it.
