Patch is based on email from Ian Kelly:
> test_get_table_description_types: This only occurs if you're running cx_Oracle 5.0.1 without the WITH_UNICODE compilation flag.  To fix it, we just need to add cx_Oracle.UNICODE to the data_types_reverse dict, mapping it to CharField.  cx_Oracle.UNICODE isn't defined in all versions of cx_Oracle, so there needs to be a check that it actually exists before referencing it.
