Policy DB contents removed on DB deadlock

When a DB deadlock occurs, the DB contents can sometimes be deleted
becasue the DB removes the Service Template object and recreates a new
one in two separate DB transactions.

This change makes sure that the object remove and re-create is in a
sngle DB transaction, so the operation will either happen or not happen
so the DB will not be cleared.

Legacy policy handling must also use the SimpleToscaProvider rather than
accessing the DB directly, as SimpleToscaProvider keeps the DB structure
correct.
