Bad rows schemas are out of date

[frbender]

Some schemas in com.snowplowanalytics.snowplow.badrows are out of date.

For example enrichment_failures says that there should be a "loaderName" when the real property is "loadername":

...
// expected
            "loaderName": {
              "type": "string",
              "maxLength": 32
            },
...

...
// actual
      "contenttype": "application/json",
      "loadername": "ssc-2.7.1-kinesis",
      "encoding": "UTF-8",
...

Similarly, "ipaddress", "refereruri", "schemacriterion", "schemakey" ... are also in the wrong casing.
