DOCM, DOTM, DOTX and XLSM provide wrong output on post functions and scheduled reports

When we have a template in docm, dotm, dotx format, and select docx as output, the report should have the same extension as the template. However, the generated report is always generated in docx format.

The same applies to the xlsm case. The generated report should have xlsm extension, but is always generated in xlsx

Note 2: This happens on Workflow Post functions and Scheduled Reports.
