**Description**

After doing a `fin update` to get 1.79.4, when doing a `fin start` in a project, our DB container seems to have a different name.  Previously it was `projectname_db_1` and now it is `abe69dd6448e_projectname_db_1` (the "abe69dd6448e" is a different uuid for each project).

**Steps to reproduce the issue:**

1. `fin stop`
2. `fin update`
3. `fin start`

**Describe the results you received:**

DB containers have a UUID added to them.  This causes the `fin db dump filename` command to error with: `Error: No such container: projectname_db_1`

**Describe the results you expected:**

I expected containers to retain their proper names.

**Output of `fin config`:**

 Comments: 
 Comment 0: @mike-potter you (not Docksal) have upgraded your docker-compose to 1.23.0. Downgrade to 1.22.0 as required by current Docksal and recreate containers.
 Comment 1: I didn't touch docker-compose.  I literally just ran the "stop", "update", "start" commands yesterday.
 Comment 2: Also, this is the docker-compose on my system:
```
% docker-compose version
docker-compose version 1.22.0, build f46880f
```
 Comment 3: @achekulaev we have at least 3 people on our team (on 3 totally different projects) suddenly hitting this so it seems to be a pretty broad issue.

@mike-potter's `fin sysinfo` output above says `docker-compose version 1.22.0, build f46880f` so I'm not sure why you think he's running `1.23.0`?
 Comment 4: Sorry, I mixed the naming change with another change that we were inundated with recently.

Anyways there is nothing that should have affected naming schema in the latest update. Most likely you have projects with colliding names. 
 Comment 5: > Most likely you have projects with colliding names.

That seems doubtful given that it's 3 people hitting it on 3 totally different projects all within 24 hours of each other, and all on projects that were previously working.
 Comment 6: Try `fin rm db` and `fin up`

 Comment 7: Among changes in 1.22 I see this

> Compose will no longer try to create containers or volumes with invalid starting characters

Is there any chance your `projectname` begins with a number?
 Comment 8: The `fin rm db` and `fin up` worked, but for others who might have this problem, WARNING: THIS WILL REMOVE YOUR DATABASE.  So be sure to back up the database first before removing.

The catch-22 here is that you cannot use the `fin db dump` command to save it because of the error.  In my case I was able to use `fin drush sql-dump >filename.sql`.  

Would be good to know if there was a way to create the db container without deleting the previous sql data volume.
 Comment 9: There is a volume, but it's not persistent. Just like `projectname_cli_home`
 Comment 10: It looks like *most* of the people here having this problem did upgrade Docker4Mac and have the docker-compose 1.23 issue.  I seem to be the only one who had the issue who has not updated docker-compose.  So a bit of mystery.

Not Docksal's fault that docker-compose made such a breaking change and looking forward to the next Docksal update (I see the PR where this is fixed).
