Don't try to delete trust if trustor not found

[huangtianhua]

1. deferred_auth_method with default value trusts
 2. create a stack with a token of projectA & user1 , a trust will be created
 3. then delete user1 in keystone, we can find the trust was deleted at the same time.
 4. delete the stack with a token of projectA & user2, after all resources have been deleted successfully, heat try to delete the trust, but an exception happened, because
the trustor(user1) is deleted, the stack went to DELETE_FAILED.
There is no need to delete trust for this situation, because the trust has been deleted already.
