This issue is part of the course hierarchy epic.

Issue Goals

• The default name for the topics format should be "New section" instead of "Topic x", where x is the section number. The current naming convention for the weeks' format should be retained (so "New section" will be used only for topics; weeks keep displaying the week date, like "10 February - 16 February").
• Add a migration process that iterates over all section records for the courses using the topics format with null names and sets the name attribute to the result of executing the format get_section_name.
• Review the page titles to guarantee they follow the expected format for each course format (for instance, it means replacing Topic with Section for the format_topics).
• Probably, once this issue is fixed, we'll need to confirm if the "Custom" checkbox available in the Edit settings page for sections is still required (at least for the Custom sections course format). It can be fixed as a separate issue, but leaving a note here to remember to check it (based on MDL-80541 proposal). --> MDL-80923

Future issues

From now on, the default section name for the topics course format won't have the section number and won't be renamed when moved. All sections will be created as "New section" whether sections or subsections.
