In https://github.com/matomo-org/matomo/blob/4.3.0-b2/plugins/SegmentEditor/API.php#L278 we trigger to rearchive the segment whenever it is updated. However, we should only do this if the definition changes (because the meaning of the report changes) or if the autoArchive changes from false/0 to true/1 (because then we'd want to make sure to have all the needed reports for in the past depending on configured setting).

This will be useful as this way we don't invalidate and rearchive reports unnecessarily.
