core: Fix fixtures tests

disk id 1b26a52b-b60f-44cb-9f46-3ef333b04a35 has rows in images table
therefore it could not be also in disk_lun_map.

Adding a new id for new lun disk instead of the old one

core: Remove disk when force remove domain

When force remove domain or storage pool, the disks and the permissions
are left in the DB tables.

the proposed fix deletes those disks and permissions from the DB as
part of the force remove stored procedure.

core: Force remove storage leaves VM permissions.

Remove of VM will not remove its permissions, since before the remove of
the permissions we remove the image from image_storage_domain_map which
vm_images_view is based on, and therefore it will not fetch this image.

The proposed fix is to create a temporary table which will contains the
vm ids and will not influenced by former operations.
