fix an issue with non-file visiting buffers #40

Hello and thank you for this package.

This MR is a quick fix for an issue I'm facing with pet-mode.

In some cases, there we can have temporary/special buffers with python-mode that doesn't visit a file (buffer-file-name is nil). In these cases, the current pet-mode gets called and cause an error.

This has been observed in mmm-mode when python-mode is used as a sub-mode, although, it can happen in other situations.

Closed because I was using a slightly old revision of pet-mode
