"InvalidArgumentException: Field amount is unknown." when accessing "/admin/commerce/reports/orders"

Problem/Motivation

Currently, when accessing "/admin/commerce/reports/orders", we get the following error:

InvalidArgumentException: Field amount is unknown.

This happens because, there is no "amount" field on the "OrderReport" entity.

Steps to reproduce

Proposed resolution

Remove the "amount" key from the "ReportsListBuilder".

Remaining tasks

User interface changes

API changes

Data model changes
