When logging an `Error` object using the clustered appender, the logged event is a JSON representation of the error, ex:
[2015-06-09 11:13:48.257] [ERROR] middleware.Security - { stack: 'Error: User is not authorized\n at Object.exec (D:\\Borealis\\demoux\\IMS\\server\\IMS\\middleware\\SecurityCheck\\Instance.js:41:14)\n [...] at applyArgs (D:\\Borealis\\demoux\\IMS\\server\\node_modules\\flow\\flow.js:9:15)\n at Function.flowState (D:\\Borealis\\demoux\\IMS\\server\\node_modules\\flow\\flow.js:39:6)\n at applyArgs (D:\\Borealis\\demoux\\IMS\\server\\node_modules\\flow\\flow.js:9:15)\n at Function.thisFlow.exec (D:\\Borealis\\demoux\\IMS\\server\\node_modules\\flow\\flow.js:94:4)\n at applyArgs (D:\\Borealis\\demoux\\IMS\\server\\node_modules\\flow\\flow.js:9:15)\n at thisFlow (D:\\Borealis\\demoux\\IMS\\server\\node_modules\\flow\\flow.js:15:4)\n at Object.exec (D:\\Borealis\\demoux\\IMS\\server\\node_modules\\flow\\flow.js:103:42)' }
The error should be formatted identically as with other appenders (e.g. only printing the stack).
This changes adds a check for a `stack` attribute on the serialized loggingEvent and unwraps the errors while deserializing it. Result is:
[2015-06-09 11:13:48.257] [ERROR] middleware.Security - Error: User is not authorized
