Context

You can currently disable the visitor profile (and visits log) feature. Then certain segments like UserID and visitorId disappear and are no longer valid.

However, segments may already exist that use one of these disabled dimensions..

Expected Behavior

The segments are deleted so that archiving doesn't fail.

Current Behavior

Archiving fails. In worst case our scheduled tasks no longer run which could have side effects such as scheduled reports and custom alerts to be no longer sent, billing being inaccurate, etc.

Uncaught exception in API: Exception: Segment 'visitorId' is not a supported segment. in /core/Segment.php:228 Stack trace: #0 /core/Segment.php(276): Piwik\Segment->getSegmentByName('visitorId') #1 //core/Segment.php(254): Piwik\Segment->getExpressionsWithUnionsResolved(Array) #2 /core/Segment.php(168): Piwik\Segment->initializeSegment('visitorId==0124...', Array) #3 /plugins/CoreAdminHome/API.php(284)

Possible Solution

Maybe delete those segments? Not sure what we're doing currently when we're deactivating a plugin whose dimensions are used in segments?
