Subject: [PATCH] Fix false debug assertion

Given the following query:

PREPARE ps FROM 'PREPARE ps2 FROM \'SELECT 1\'';

The debug assertion is hit even though this is valid, albeit unsupported,
SQL. An optimization would be to ignore the query if the prepared
statement type is another prepared statement.
