[ermine] Refactor AppModel for unittest
This change adds a unittest for AppModel, the main
respository of application level state in Ermine. The AppModel class
is refactored to be able to take mock depedencies injected into its
constructor.
- minor renamings and tweaks.
- tighten logic to confirm to expected behavior, with test coverage.
Bug: 49908
Testing: Adds a unittest for almost 100% coverage on AppModel class.
