ApiException causes no attribute 'trace_token' exception when trying to print it

[jmrodri]

The ApiException class has an optional http_resp parameter. It will then use the alternate construction which does not set the trace_token attribute.

Here is a reproducer:

from docusign_esign import ApiException
e = ApiException(status="status", reason="reason")
print(e)

Here is what I got when running it:

In [1]: from docusign_esign import ApiException

In [2]: e = ApiException(status="status", reason="reason")

In [3]: print(e)
---------------------------------------------------------------------------

     41         if self.headers:
     42             error_message += "HTTP response headers: {0}\n".format(self.headers)

AttributeError: 'ApiException' object has no attribute 'trace_token'

After the patch it works:

(status)
Reason: reason
Trace-Token: None
Timestamp: None
