bug(versioned): Fix tracking impls across multiple containers for the same version #1302

Discovered in #1294.

• The tracking impls per each container assume they are the only container which need to access to ChangedValues' upgrades and/or downgrades and currently removes the list of ChangedValue for a particular version. The code must only remove the entire entry once the list inside is empty. Otherwise, other containers won't be able to access the tracked changes.
• Each tracking impl only looks and removes the changes which matched to the expected JSON path. Unmatched JSON paths currently lead to a panic. They should instead be ignored.

I'm interested to work on this.
