CORDA-1699: Restore binary compatibility for UniqueIdentifier class. (#3505)

* Update JarFilter to remove certain annotations from primary constructors.
* Enhance unit tests for deleting constructors.
* Update the documentation to explain how to handle non-deterministic default
constructor parameters.
* Reduce the base logging level of SanitisingTransformer to DEBUG.
* Simplify the execution of repeatable ClassVisitors.
* Simplify Gradle usage slightly.
* Add test for deterministic UniqueIdentifier.
* Update README to cover handling default parameters.
