Remove line from metering_container_image_spec and FIX CI failure

[lpichler]

Fixes CI failure
https://travis-ci.org/ManageIQ/manageiq/jobs/426890608#L1472
after removals in #17934 and #17962

the line was adding dynamically column metering_used_cost to class MeteringContainerImage as descendant of Chargeback.

and this column has been returned by

manageiq/spec/models/miq_report/formats_spec.rb

Line 28 in 4c32131

let(:columns) { Chargeback.descendants.collect(&:virtual_attributes_to_define).inject({}, &:merge) }

a we don't have defined formatter currency_precision_2 for this columnmetering_used_cost.

Please merge if any other unrelated sporadic failure will occur.
