PATCH: don't start a vi change from emacs mode

If put-replace-change is used from emacs mode, it starts a vi change.
This is mostly harmless, or at least was before this was used by the
terminal cursor changing to tell vi mode apart from emacs mode. This
patch makes this conditional.

vi-backward-delete-char also has a similar condition. Most widgets in
zle_vi.c don't but I can't see much else that would warrant it.
