Updated thanks to @James KO Steps are very similar:

... (on the right panel) -> Snapshots tap -> Settings (top tab on detail view) -> Auto-save current state to Quickboot dropdown

end update

In the latest version of the Android Studio (I am running 3.1.2), it is no longer in the AVD Manager settings. I found it under Extended Controls on emulator itself.

1. Start emulator
2. Click three dots (...) on emulator panel
3. Go to Settings -> General, towards the bottom "Save quick-boot state on exit for AVD:"
