In consistent with lispy for "[" and "]" in strings or comments

[yangsheng6810]

In lispy, typing "[" or "]" in a string or a comment will go out of the current string, calling lispy-left or lispy-right, while in evil-lispy, it will self-insert "[" or "]". It seems related to

(evil-lispy/defnonstring-action evil-lispy/insert-to-lispy-right
  evil-lispy/enter-state-right)
