using --experimental-enabled=text-search with old mg_lib prevents startup

[dhawleyGadzoom]

Memgraph version
docker image memgraph/memgraph-mage:1.16-memgraph-2.16

Environment
Controlled by docker-compose.yml

Describe the bug
When I enable --experimental-enabled=text-search in docker-compose.yml and replace the old container (but not the mg_lib volume), the new container fails to start up. It gives the message "Tried to retrieve an unknown database "memgraph"."

To Reproduce
Steps to reproduce the behavior in a very minimal way:

1. Run the following docker-compose.yml (docker-compose up)

version: '3.3'
services:
  memgraph:
    image: memgraph/memgraph-mage:1.16-memgraph-2.16
    ports:
      - "7687:7687"
      - "7444:7444"
    command: []
    volumes:
      - mg_lib_1:/var/lib/memgraph
      - mg_log_1:/var/log/memgraph
      - mg_etc_1:/etc/memgraph
volumes:
  mg_lib_1:
  mg_lib_2:
  mg_log_1:
  mg_etc_1:

2. Delete the container
3. Run the following docker-compose.yml (docker-compose up). Note that this is the same as the above except with command --experimental-enabled=text-search

version: '3.3'
services:
  memgraph:
    image: memgraph/memgraph-mage:1.16-memgraph-2.16
    ports:
      - "7687:7687"
      - "7444:7444"
    command: ["--experimental-enabled=text-search"]
    volumes:
      - mg_lib_1:/var/lib/memgraph
      - mg_log_1:/var/log/memgraph
      - mg_etc_1:/etc/memgraph
volumes:
  mg_lib_1:
  mg_lib_2:
  mg_log_1:
  mg_etc_1:

At this point, I the docker-compose up command prints memgraph_1 exited with code 139 and the container (which is now stopped) ends its logs with Tried to retrieve an unknown database "memgraph".

Expected behavior
I expect the container from step 3 to start up and stay running. If there were any existing data in mg_lib_1 (like there is for my actual, non minimally reproducible setup), then I would expect to be able to use the experimental text search on the existing data.

Additional context
Note that the container starts fine if it's using a new mg_lib volume. For example, after running the steps detailed above to reproduce the bug, I am able to start a container just fine with the following (the same but using the mg_lib_2 volume instead of mg_lib_1):

version: '3.3'
services:
  memgraph:
    image: memgraph/memgraph-mage:1.16-memgraph-2.16
    ports:
      - "7687:7687"
      - "7444:7444"
    command: ["--experimental-enabled=text-search"]
    volumes:
      - mg_lib_2:/var/lib/memgraph
      - mg_log_1:/var/log/memgraph
      - mg_etc_1:/etc/memgraph
volumes:
  mg_lib_1:
  mg_lib_2:
  mg_log_1:
  mg_etc_1:

If I understand correctly, this means that in order to use the text search with my existing data, I would need to export the data, switch volumes, and import the data, which is not ideal.
