Cache flush after database reset (#14873)

When starting the app on a fresh database reset the cache would be
filled with empty flat field metadata maps
Because the reset command hack through the repository directly in order
to create views and stuff
implemented an iso flush as the one existing initially
added it to a workspace deletion tambien
```
{
   byId: {],
   universalIdById: {}
}
```
