Subject: [PATCH] chore(agoric-cli): Condense `agoric wallet show` output

Render empty purses/usedInvitations/offers on one line rather than three:
```diff
 {
   "purses": [
     ["board0074",0]
   ],
-  "usedInvitations": [
-
-  ],
-  "offers": [
-
-  ]
+  "usedInvitations": [],
+  "offers": []
 }
```
