Ignore warning on empty result (elasticsearch filter)

Description

Hi,

When I have a empty result for a query in elasticsearch filter, I get a lots of warning message "<NoMethodError: undefined method `[]' for nil:NilClass>"

1 2 3 4 5 elasticsearch { hosts => [ "localhost" ] query => "test:%{test}" fields => [ "test", "test_tmp" ] }

These messages increase the writing to the Logstash logfiles.
