Unescaped table name during detection of table structure

Engine CONNECT doesn't escape table name when autodetecting table structure for TABLE_TYPE=MYSQL using SHOW columns FROM source_table.

That means that following query fails:

CREATE TABLE new_table ENGINE=CONNECT TABLE_TYPE=MYSQL CONNECTION='mysql://user:pass@hostname/db_name/85e3adc9789111e7960b00163e6c8245'

Escaping table name within the CREATE doesn't help. The CREATE works, but the engine retrieves data using invalid double escaped query

SELECT * FROM ``85e3adc9789111e7960b00163e6c8245``.

The create works fine with explicit definition of columns.
