* fix: assign instance ID to aggregate ID when converting from v1 to v2 feature
This change fixes a mismatch between v1 and v2 aggregate IDs for instance feature events.
The old v1 used a random aggregate ID, while v2 uses the instance ID as aggregate ID.
The adapter was not correctly mapping, which resulted in the projections.instance_features table being filled with wrong instance IDs.
Closes#7501
* fix unit test
