Codec not considered

[guenhter]

• Version:
  7.2.0

• Operating System:
  Debian 9.9

• Config File (if you have sensitive info, please remove it):

input {
    stdin { }
}

output {
    websocket {
        port => 8080
        codec => line { format => "test"}
    }
    stdout {
        codec => line { format => "test"}
    }
}

• Steps to Reproduce:
  Post a message:

• The stdout gets results in "test" but the websocket output results in a full output with all the builderblate tags like version, time, ...
