doesn't work with evil's very-magic search module

[Troy Hinckley]

if you set the following variables

         evil-search-module 'evil-search
         evil-magic 'very-magic

evil-multiedit no longer works and gives the error evil-ex-search-find-next-pattern: Invalid regexp: "Invalid regular expression". It looks like this is because evil-multiedit is relying on evil-ex using emacs flavor regex.
