It seems that you are running multiple instances of the emulator suite for project <project-name>. This may result in unexpected behavior

### [REQUIRED] Environment info

**firebase-tools: 9.16.0**

**Platform: Windows 10 21H1*

### [REQUIRED] Steps to reproduce

Start the emulators, press CTRL + C and wait for it to say shut down. Start it back up and look for the below message:

> ! emulators: It seems that you are running multiple instances of the emulator suite for project plant-order-form. This may result in unexpected behavior.

### [REQUIRED] Expected behavior

The emulators shut down cleanly everytime

### [REQUIRED] Actual behavior

It seems that the emulators don't cleanup properly

Some additional notes:
- I work on multiple Firebase projects on my machine. Each time I start up the emulator, it starts it for all the projects I've worked on so far
- Whenever I close the emulators with CTRL+C two terminals are still left open (see images below). I always have to manually close them for the emulator to restart successfully
- Perhaps a different problem entirely, it doesn't export to the folder it derived the import from. It'll read in from `./mock` but always fail to export and dump the export at my project root(see third image)

These are by no means critical problems, just really inconvenient. I always have to look at what port the emulator is started on to make sure I'm looking at the correct UI.
