Some apps have an invalid `has_binary` field

[sjp4]

Example: https://appstore-api.rebble.io/api/v1/apps/id/69a30474521b3b000990cadd (which is also present in home feed for apps: https://appstore-api.rebble.io/api/v1/apps/id/69a30474521b3b000990cadd) has:

"basalt": {
          "firmware": {
            "major": 3
          },
          "has_binary": {

          },
          "supported": true
        },

where is_binary should be a boolean, so the app is having trouble parsing that field as an empty object (null would be fine if we don't have the data to populate it).

Every other app in the home feed looks good e.g.:

"basalt": {
          "firmware": {
            "major": 3
          },
          "has_binary": true,
          "supported": true
        },
