Removed UID validation when any of the study, series or instance UIDs…

… are same (#3257)

* Removed UID validation when any of the UIDs are same

* Fix failed tests

* Changes from review comment, nits

* Changes from review comment, nits

* Added test for V2

* Remove substiture for IElementMinimumValidator, skipping failed tests
