record: omit meaningless 'qrefresh' suggestion at 'hg qrefresh -i'

Before this patch, 'hg qrefresh -i' under non-interactive mode
suggests 'use qrefresh instead', and it obviously meaningless.

To omit meaningless 'qrefresh' suggestion at 'hg qrefresh -i', this
patch specifies 'None' for 'cmdsuggest' argument of 'cmdutil.dorecord()'.
