Incorrect error type and error message raised by phoenixdb (python) driver

When users use execute SQL against Phoenix tables using pythondb, if SQL has syntax errors, those are not reported correctly.

Eg. error message:

(phoenixdb.errors.InternalError) ('', 1, '00000', None)

when the following query was executed

select * from A.B where ROW_ID == 24

The actual error message from PQS, transferred using Avatica/PQS proxy includes the entire stack trace.
