NestTemplateMigration converts the legacy NestTemplatePath template into the nest defaults file when the template exists and no defaults file does, and says whether to clear the setting (converted or nothing to convert) or the warning to show when the conversion failed, which keeps the setting. A settings-map overload clears it to the empty text WinForms stores, so it runs once. WinForms' MainWindowSettings now calls it and still shows the same warning.
