Use more numerically stable log1p in examples/scanvi/scanvi.py

Found using TorchFix https://github.com/pytorch-labs/torchfix/

Thank you for the fix! Interesting tool. Was this the only autofix found by TorchFix?

For this specific rule TorchFix has only linter, not autofix.
So the issue was found by the tool, and I changed the code manually.

Thank you! I've made a PR with the fixes for deprecated torch functions.
