JSON "null" matches empty string in LLD filters

      Suppose we send a JSON like the following to Zabbix server:

      {
          "data": [
              {
                  "{#MACRO}": "macro",
                  "{#FILTER}": null
              }
          ]
      }
      

      If we filter by {#FILTER}, then "null" will be processed like an empty string and will match regular expression "^$". Instead, the filter should fail.

      The reason for the behavior above is that our JSON parser currently parses JSON null as an empty string.
