systemvm-registration: update seeded template_store_ref sizes

[rp-]

Description

Pre-seeded template storages always had there pre initialized 0 sizes and would never be updated.
This makes later problems, when the primary storage should pre-allocate the volume as it doesn't know the size
and would fail or maybe try to delay the allocation until the agent code knows the size.
This updates the sizes from the template.properties files on the validateIfSeeded check.

The issue was found while reviewing #10132
