fix: querying virtual fields deeply with draft: true (#12868)

Fixes an issue when querying deeply new relationship virtual fields with
`draft: true`. Changes the method for `where` sanitization, before it
was done in `validateSearchParam` which didn't work with versions
properly, now there's a separate `sanitizeWhereQuery` function that does
this.
