Apparently, Virtuoso forcefully casts xsd:int into xsd:integer if you try to insret with SPARQL via Conductor. So better to always insert cr:byteSize always as xsd:integer, as it is anyway a super-type for bith xsd:int and xsd:long. Another issue is that Virtuoso-Sesame driver wrongly returns xsd:int even if it's xsd:integer in the triplestore. So taking this into account in unit tests. Refs #19332.
