Handle a just deleted db in auto-purge plugin
Noticed this in production logs:
```
database_does_not_exist at mem3_shards:load_from_db/1(line:463)
<= mem3_shards:load_opts_from_disk/1(line:436)
<= mem3:props/1(line:122)
<= fabric_auto_purge:get/1(line:22)
<= couch_auto_purge_plugin:ttl/2(line:195)
<= couch_auto_purge_plugin:db/2(line:66)
```
The plugin crashes and resumes from the checkpoint and makes further
progress,
but since this is an expected case it might be a bit nicer to anticipate and
handle it cleaner.
