Schema+Json looses array type when there's a reference involved [DATAREST-788]

Wallace Wadge opened DATAREST-788 and commented

Consider:

  class Account{ 
    @OneToMany
    @ReadOnlyProperty @Reference
            List<ApiAccountEntry> accountEntries = new LinkedList<>();
}

Asking for schema+json returns

"accountEntries": {
  "title": "Account entries",
  "readOnly": true,
  "type": "string",
  "format": "uri"
},

while if @Reference isn't defined in the model we get:

"accountEntries": {
      "title": "Account entries",
      "readOnly": true,
      "type": "array",
      "items": {
        "$ref": "#/definitions/apiAccountEntry"
      }
    },

Note that we've lost the "array" bit.

Therefore if we have @Reference, we don't know from the returned type that we have a @OneToMany (as opposed to for eg @ManyToOne).

If you agree that this is a bug, I'll submit a PR to fix.
