Revert "[IMP] account_financial_report_webkit: in test, work around demo periods issue in 7.0"

This revert is done intentionally to remove a workaround for 7.0 only,
and not have it back in subsequent 7.0 -> 8.0 merges.

For details see
https://github.com/OCA/account-financial-reporting/pull/5#issuecomment-56939862
