This appeared after introduction of KProperty in delegated property convention
methods. If a KProperty1 instance is created while constructing a KClassImpl
instance before assigning the 'jClass' field, an NPE is thrown because the
constructor of that KProperty1 instance tries to lookup the declaring class of
the property, which in some case happens to be the exact KClassImpl we're
constructing. No test added because I was not able to reproduce the behavior in
an isolated environment
