Fix ODBC SQL Error string decoding (#10207) [backport]

Browse Source 
ODBC Errors were presented to the users as a sequence of characters.
I.e.:

    >test_oracle.exe

    Error: ['H', 'Y', '0', '0', '0', '\x00', '\x00', ...]

    test_oracle.nim(15)      test_oracle
    test_oracle.nim(8)       test_oracle
    db_odbc.nim(534)         open
    db_odbc.nim(168)         dbError
    Error: unhandled exception: ODBC Error [DbError]

This patch fix the string decoding, creating a real string:

    >test_oracle.exe

    Error: HY000 [Oracle][ODBC][Ora]ORA-12541: TNS:no listener

    test_oracle.nim(15)      test_oracle
    test_oracle.nim(8)       test_oracle
    db_odbc.nim(534)         open
    db_odbc.nim(168)         dbError
    Error: unhandled exception: ODBC Error [DbError]
