elm_config: repair configs
in eec7bc458eee333fd7237a3bd43e8c2c884f21ca the epoch offset was edited,
which seems to be wrong, as this caused every single config to be
deleted. This also updates the configs in the elementry base configs
as they have been forgotten.
This brings back the ability to edit the config in elementary_config.
