[#85] Fix empty object output for Error objects

[skgndi12]

Resolves #85

Changes

• Implement a function to convert error properties into plain objects.

Example Scenario

// Error log
logger.error('error log', { error: new Error('test') });

// CustomError log
logger.error('custom error log', {
error: new CustomError({
  code: AppErrorCode.INTERNAL_ERROR,
  cause: new Error('cause'),
  messages: ['custom error message'],
  context: { foo: 'bar' }
})
});
