QN: Apps metadata is empty

Extrinsic: `appWorkingGroup.setStatusText(statusText)`
Block: [6,133,838](https://explorer.joystream.org/#/blocks/6133838)

## Expected result
1. Message is displayed at https://dao.l1.media/#/working-groups/apps
2. Message appears in query result to https://query.joystream.org/graphql
```
query {
workingGroupMetadata {
about
status
statusMessage
groupId
}
}
```

## Result
1. Pioneer query result (`operationName: "GetWorkingGroup"`):
```
"data": {
"workingGroupByUniqueInput": {
"id": "appWorkingGroup",
"name": "appWorkingGroup",
"budget": "14999999980332300",
"metadata": null,
"workers": [
...
],
"leader": {
"membershipId": "515",
"isActive": true,
"__typename": "Worker",
"id": "appWorkingGroup-10",
"runtimeId": 10,
"stake": "150000000000000",
"rewardPerBlock": "100"
},
```
2. QN result:
```
"workingGroupMetadata": [
{
"about": "Builders working group builds&maintains Joystream software and manages technical operations of the DAO.",
"status": "Full steam ahead",
"statusMessage": "Full steam ahead",
"groupId": "operationsWorkingGroupAlpha"
},
{
"about": "Content Working Group monitors content",
"status": "On the go",
"statusMessage": null,
"groupId": "contentWorkingGroup"
},
{
"about": "Content Working Group monitors content",
"status": "On the go",
"statusMessage": null,
"groupId": "contentWorkingGroup"
}
]
```
Alternative QN:
- https://query.joyutils.org/graphql: `"message": "connect ECONNREFUSED 172.18.0.11:5432",`
- https://query.l1.media/graphql: Not fully synced. Total processing time is about 2 weeks.
`INFO: Last block: 8453807 : 6450580 blocks behind`

## Interpretation
Either the processor is behind / failing or group metadata isn't being updated.
