pytest: catch rare exception for random tables test

On rare occassions a SELECT on a DROPpped table throws
cassandra.ReadFailure instead of cassandra.InvalidRequest. This could
not be reproduced locally.

Catch both exceptions as the table is not present anyway and it's
correctly marked as a failure.
