Warning message for versions is a little confusing

[jasonpolites]

I recently updated the emulator, and when I tried to execute a command I got this message:

The version of the currently running Emulator is lower than that of the installed CLI (1.0.0-alpha.11). Please shutdown any running Emulator processes and restart using the installed CLI.

OK.. that's cool, but it's not super-clear what it's telling me to do. Please shutdown any running Emulator processes.. am I supposed to manually kill the process? Recommend re-phrasing to:

"The version of the currently running Emulator is lower than that of the installed CLI (1.0.0-alpha.11). Please manually terminate any running Emulator processes, then restart using the CLI."

Also there's an extra space between "Emulator" and "is" in the current message.

Longer term we should look at how we can do this for the user, perhaps with a Y/N warning/question (assuming we can deduce the process ID from the file system etc)

Actually... this feels like a bug. I can't start the emulator at all now. I've confirmed I have no running processes, but I still just get the warning.

[jasonpolites]

Maybe manually killing the process left the PID file on the file system?

You don't have any node processes at all? Also, try deleting ~/.config/configstore/@google-cloud/functions-emulator/

Maybe manually killing the process left the PID file on the file system?

Possibly, when you use the CLI to stop the Emulator, the PID is removed. I should update the Emulator to remove its own PID from the filesystem when the process exits.

The fix in that commit 4da522b is likely to not work as the user can't invoke the functions CLI without the warning, and hence can't call functions kill

[jmdobry]

I removed the line that prevented the user from calling functions kill

Done
