Issue Description

• Expected behavior : if I call org.nd4j.autodiff.samediff.SameDiff#var(java.lang.String, org.nd4j.linalg.api.ndarray.INDArray) inside different name scopes, it should work.
• Actual behavior : if I call org.nd4j.autodiff.samediff.SameDiff#var(java.lang.String, org.nd4j.linalg.api.ndarray.INDArray) inside different name scopes, it fails with java.lang.IllegalArgumentException: Another variable with the name "..." already exists..

Version Information

• Deeplearning4j version - SNAPSHOT-1.0.0
• Platform information - Windows 11
• CUDA version - N/A
• NVIDIA driver version - N/A

Additional Information

Seems like the method which fails does not re-use the logic in org.nd4j.autodiff.samediff.SameDiff#var(java.lang.String, org.nd4j.autodiff.samediff.VariableType, org.nd4j.weightinit.WeightInitScheme, org.nd4j.linalg.api.buffer.DataType, long...) which takes into account the name scopes.
