[Bug][fix]Mod git's color.status to auto @bootstrap.sh

Bug description:
    vim-fugitive shows escape color code instead of showing color
        eg. ^[[31m....^[[m

Bug analysis:
    Previous I set color.status to always in order to pass color to sed
    in bootstrap.sh
    git config --global color.status always

    However, only deleting [color] section in gitconfig won't solve the
    problem.

Bug Solution:
    reset color.status to auto manually
    git config --global color.status auto
