Broken REST API

[DGabri]

lua/rest/v2/get/alert/top.lua

Fails when invoked, instead of returning an error code, it returns rubbish

curl -u admin:admin -H "Content-Type: application/json" -d '{"ifid": "0"}' http://localhost:3000/lua/rest/v2/get/alert/top.lua

/ntopng/scripts/lua/modules/alert_store/alert_store.lua:1814: bad argument #1 to 'for iterator' (table expected, got string)

The issue should now be fixed, however consider the following, if you want ALL the alerts, you need to add the status filter to the query, otherwise only the "important" alerts are displayed.
I'd suggest specifing in the Documented rest api that by default only the important one are displayed ("historical"); if all the alerts needs to be displayed, the filter is "all" otherwise only the engaged one is "engaged":

biscosi@devele:~/ntopng$ curl -u admin:admin1 -H "Content-Type: application/json" -d '{"ifid": "11", "status": "any"}' http://localhost:3000/lua/rest/v2/get/alert/top.lua
