Fix the tree view's subpar tree ID behavior

[bwateratmsft]

The rapidly-changing tree ID causes some misbehaviors. For example when a container moves from "a few seconds ago" to "a minute ago" it changes IDs, so if the user right-clicked the container before the change to run a command, then it will prompt them to choose--this is redundant and annoying.

Ideally only the resource ID/name should be part of the tree ID. But, we need a way to cause a UI refresh when other data (such as state, etc.) changes.
