Fixed error 500 when downloading asset acceptance report. [sc-19555]

[inietov]

Description

When looking at the Unaccepted Assets report, if the user click on the Download All button, an exception occurs because it's trying to got into a relationship that doesn't exist if the unaccepted item is not an asset (accessory, consumable, etc), so I filter those types from the downloaded report so it matches to the on-screen one.
