The previous fix ignored any pyenv command found in $PATH while on
WSL, regardless of whether it was correctly set up or not.
This change only ignores the pyenv command if it's proved to come
from pyenv-win by looking at its full path.
This change fixes the setting of $PATH for pyenv and its shims, while warning
the user about non-interactive shells.

This is needed if in between the update of `$PATH` the `$commands` parameter hasn't
been updated, i.e. if there was no `rehash` or `hash -rf` or automatic rehash.
