Problem/Motivation

#2500535: Upgrade path for Tracker 7.x → introduced a migration for the tracker module. It should be a very simple migration since it's one of the very few that's pretty much just copying a DB table.

  1. The first problem: dependencies. Even though #2500535-5: Upgrade path for Tracker 7.x → .10 asked for migration dependencies to be added and #2500535-11: Upgrade path for Tracker 7.x → added those, they're wrong.
  2. The second problem is far worse: nothing about the migration is correct 😨. The tests don't test the migration, but the source DB. The migrations themselves try to migrate into user and node entities, which makes no sense.

Steps to reproduce

Proposed resolution

While this migration is not needed running it does not cause problems on the destination. See #5 and #10.
Leaving as postponed because it can be done when this is moved to the contrib project.

Original proposed resolution

    This is a test.

    But it tests not the migration.

    It tests the _source DB_ 😳
