Fix testClassObjectCopiedFieldObject test

Fix of the test
PsiCheckerTestGenerated$DuplicateJvmSignature$Fields.testClassObjectCopiedFieldObject
additionally fixed the bug with blinking this test example in IDEA with UL classes enabled.

The story:
Extra diagnostics could be requested for any KtClassOrObject but for _nested_  classes result may depend on outer class members signature collecting. So the the order of outer/nested diagnostic reporting takes matter.
So for nested classes/objects we have to gen members of outer classes.
