Denis Zharkov 1780f57265 Fix mutable collection stub methods generation for corner case
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
