Lost editing when browser communication fails.

[sam-s]

When I hit C-c C-c, the buffer is killed even if the browser tab which started the edit is already gone. I lost my work many times this way. It appears that there is a 5yo pr https://github.com/stsquad/emacs_chrome/pull/66 which addresses the problem. My current "solution" is to set nokill to t in edit-server-done.
