Previously, only unipc, dpm++, and dpm++_sde schedulers preserved custom input sigmas exactly. Other schedulers such as (euler, lcm, deis, etc.) would transform or modify the sigmas through their set_timesteps() methods, causing inconsistent behavior.

I'm unsure if this was the intended behavior however since it was deliberately zeroing out the sigmas if present:
sigmas=sigmas[:-1].tolist() if sigmas is not None else None
