Use mutable lists before deserialization of project structure

The problem is that we perform xml deserialization using intellij
 mechanism which tries to clear target object if it isn't unmodifiable
 (see CollectionBinding.isMutableCollection). This check fails for
 kotlin.EmptyList (emptyList()) which then cause exception
