* revert_data only runs when the admin chooses to delete the
* extension data, not just when the extension is disabled.
* If they simply disable the extension, we *must* ensure
* that our custom notifications are purged/disabled, as
* otherwise the board will continue trying to use them even
* though their code is disabled.
