Add more detailed exception message

[B-Stefan]

I got the problem that the neo4j-driver throws an expcetion in the travis enviroment that could be improved. Especially the message ;)  

I got the following error message:

Traceback (most recent call last):

neo4j.v1.api.CypherError: Internal error - should have used fall back to execute query, but something went horribly wrong

Do you have any idea what could cause this exception?

Hi @B-Stefan,

I tried to search in the whole driver codebase, but I did not find anything related to this error message. And also you seems on a old 1.1 driver, could you try to update to the latest driver and retry your test?

I am closing this issue as I cannot find the error message from the driver code. Either because we already fixed or it is an external error.

Best, Zhen
