When a resource is created, the :ensure parameter should be set to
'present' so that exists returns true. In addition, the whole hash
should be cleared when a resource is deleted, otherwise subsequent
access might look up stale values. This change ensures property_hash is
updated in create/destroy accordingly.
This change also fixes the incorrect handling of "project" property
in nova_flavor which is causing unexpected update.
Finally, the ignored unit tests are fixed, to test the above fixes.
