call s:py_core_load() evan though no python environment

[wedgwood]

Hi Rykka,

I found some problem when starting vim with the environment without python. It blame that error throws when function colorv#init..47_py_core_load.

I found some clue in the script autload/colorv.vim

line3492:

call s:py_core_load()

It runs whenever g:ColorV_has_python is set.

I guess there is something mistake here.
