After upgrade: `microceph cluster list`: Daemon not yet initialized

# Issue report

## What version of MicroCeph are you using ?

```
installed: 0+git.4a608fc (793) 96MB in-cohort,held
```

## What are the steps to reproduce this issue ?

1. Upgrade to 0+git.4a608fc
2. Run `microceph cluster list`

## What happens (observed behaviour) ?

On 2 servers:

```
root@mc11:~# microceph cluster list
Error: Daemon not yet initialized
root@mc12:~# microceph cluster list
Error: Daemon not yet initialized
```

On one different server (cluster of 3), microceph snap would not start at all

```
Error: Unable to start daemon: Daemon failed to start: Failed to initialize trust store: Failed to parse local record "". Found empty certificate
```

## What were you expecting to happen ?

No issue with certificates missing.

## Additional comments.

I was able to fix it by copying `/var/snap/microceph/common/state/truststore/` from another server. It seems the upgrade removed the truststore (not more yaml find inside).
