State-Based Propagation Improvement

This PR fixes and improves the state-based change propagation. It prepares for state-based propagation of changes in Java by the Java code monitor.

Fixes essential bugs in the default state-based propagation strategy preventing Java state comparison
Adds support for creating and deleting resources rather than only for their modification and extends the API accordingly
Properly extracts the information passed to the VirtualModel to perform state-based change propagation
Adds a bunch of basic test cases for the state-based change propagation

⚠️ depends on #455 to ensure that UUIDs for readonly resources work properly for state comparison.

Closes #269
