Env autoactivate doesn't work when using find-file

[GrqPnegre]

When conda-env-autoactivate-mode t and opening a file in a directory containing environment.yml for the first time, the conda environment is not activated.

It appears that conda--switch-buffer-auto-activate is not being called as part of find-file.

Possible fix:
Add conda--switch-buffer-auto-activate to find-file-hook.

I've had success adding conda--switch-buffer-auto-activate to the window-selection-change-functions hook, which also means I can remove the advice to switch-to-buffer. Does anyone know of cases where this wouldn't work as expected?

One downside is that this does cause a lot of message spam. If we did go for this option, I'd rewrite some of the switching functions to avoid calling message quite so much (perhaps writing to a hidden debug buffer?).
