Fixes deprecation warnings in `test_optim.py` (#67954)
Summary:
Catches deprecation warnings when we call `scheduler.step(epoch)`
in tests.
Removes duplicate parameters to optimizers unless we are specifically
testing for that
Fixes https://github.com/pytorch/pytorch/issues/67696
There is one warning remaining when I run this locally -- however that is due to the implementation of the `SequentialLR` Scheduler. I will open a new issue relating to that.
