When attempting to export XML through the "Tools > Exports" menu with the selection "Choose what to export > All," the process does not include the export of created templates.

@heymehedi thanks for your PR! I'm not sure I'm the best person to have a look at it, as I'm not very familiar with the Exporter. Cc @SergeyBiryukov

Patch needs testing first.
