Installing app on the emulator and restarting the container makes the emulator crashes

## 🐛 Bug Report

Operating System:

CentOS 7

Docker Image:
budtmo/docker-android-x86-12.0

Docker Version:
Docker version 19.03.3, build a872fc2f86

Docker Command to start docker-android:
`docker run --privileged -d -p 8055:6080 -p 5554:5554 -p 5555:5555 -e DEVICE="Samsung Galaxy S10" --name emulator-container-monkey-5555 budtmo/docker-android-x86-12.0`

What I did:

1. `docker stop emulator-container-monkey-5555`
2. Install app on the emulator
3. `docker start emulator-container-monkey-5555`

## Expected Behavior
Emulator should show up with app installed

## Actual Behavior
Emulator is missing at noVNC viewer. Possibly the emulator is crashed.

## Additional Note
If I don't install app and just web browse via chrome, after restarting the container, the emulator shows up and the browser history remains still.

My Question here is do I need to attach volume?
If so, could anyone tell me which directory I should mount?
