This patch mutes the following test categories:
* Tests with java dependencies (System class,
java stdlib, jvm-oriented annotations etc).
* Coroutines tests.
* Reflection tests.
* Tests with an inheritance from the standard
collections.
The problem is that
`override fun remove(element: E): CollectionWithRemove<E>`
seems to be illegal from Java's point of view, while it's OK for JVM
These declarations have the same signature (return type is isgnored)
- override fun remove(element: E): CollectionWithRemove<E>
- override fun remove(element: E): Boolean
When we meet such declaration we choose random declaration for fake override in synthetic class
that may lead to signature clash
