emacs: revert cab1ac6e68 (#7765)

Browse source 
Revert cab1ac6e68

The change from the above commit breaks opening a new emacs frame if
there isn't a existing frame open.

When emacs is running in daemon mode, there will always be a frame
associated with the daemon, even if there are no visible frames.

The lisp function `frame-list`, will always return 1 frame.
```
emacsclient --eval '(frame-list)'
(#<frame F1 0xa3c680>)
```

When an real frame is open, two frames are reported by the `frame-list`
function.
```
emacsclient --eval '(frame-list)'
(#<frame F1 0xa3c680> #<frame emacs Prelude - ~/oh-my-zsh/plugins/emacs/emacsclient.sh 0xf50e10>)
```
