Fix an error in PR #6243.

TESTING

• Use production database
• Try the report: Finance > Report > Open Debtors
  • Try it in the enterprise currency (default), and note a few numbers including the final total at the bottom of the report. Also, no exchange rate should be listed under the title.
  • Try it with some other currency and verify that the new numbers are correct. The exchange rate used should be listed at the top of the report (under the title).
