RestService: missing index log message displays wrong setting

[sawyercade]

In RestService.findPartitions(), if reads/writes are requested on an index that does not exist, es.index.read.missing.as.empty is checked to determine whether further action should be allowed. However, when further action is not configured as allowable, the log message displays Index [index/type] missing and settings [es.field.read.empty.as.null] is set to false.

The field name displayed in the log message should be es.index.read.missing.as.empty, not es.field.read.empty.as.null.

Fixed. Thanks!
