[New-bugs-announce] [issue27897] Avoid possible crash in pysqlite_connection_create_collation

[Xiang Zhang]

New submission from Xiang Zhang:

When supplied a custom string with upper returning a non-string, pysqlite_connection_create_collation will fail assertion and crash. Serhiy, I think we can use the same way in set_isolation_level to avoid this.
