Revert "Add --wait to the test command inside the bundle archetype's met...

...adata.xml."

This reverts commit 0ee1242f83f3d6b9e5fc415ba42557291164d363.

The original change was not the appropriate fix.  The "waiting" during a test should be in the process that kicks off the test launch, thus the test launch itself does not need to wait.  With this change, testing a bundle against oozie will immediately return (since the code to poll status is pegasus-specific).  Opening a separate ticket for that feature.
